- * FUNCTION
- *	vector double _acosd2(vector double x)
- *
- * DESCRIPTION
- * 	Compute the arc cosine of the vector of double precision elements 
- * 	specified by x, returning the resulting angles in radians. The input
- *      elements are to be in the closed interval [-1, 1]. Values outside 
- *      this range result in a invalid operation execption being latched in 
- *	the FPSCR register and a NAN is returned.
- *
- * 	The basic algorithm computes the arc cosine using PI/2 - asind2(x). 
- *      However, as |x| approaches 1, there is a cancellation error in 
- *	subtracting asind2(x) from PI/2, so we simplify the evaluation
- *	instead of layering acosd2 on top of asind2.
- *
- * 	This yields the basic algorithm of:
- *
- *	   absx = (x < 0.0) ? -x : x;
- *	 
- *	   if (absx > 0.5) {
- *	     if (x < 0) {
- *	       addend = SM_PI;
- *	       multiplier = -2.0;
- *	     } else {
- *	       addend = 0.0;
- *	       multiplier = 2.0;
- *	     }
- *	
- *	     x = sqrt(-0.5 * absx + 0.5);
- *	   } else {
- *	     addend = SM_PI_2;
- *	     multiplier = -1.0;
- *	   }
- *	
- *	    x2 = x * x;
- *	    x3 = x2 * x;
- *
- *	    p = ((((P5 * x2 + P4)*x2 + P3)*x2 + P2)*x2 + P1)*x2 + P0;
- *	 
- *	    q = ((((Q5 * x2 + Q4)*x2 + Q3)*x2 + Q2)*x2 + Q1)*x2 + Q0;;
- *	
- *	    pq = p / q;
- *	
- *	    result = (x3*pq + x)*multiplier - addend;
- *
- *	Where P5-P0 and Q5-Q0 are the polynomial coeficients. See asind2 
- *	for additional details.

- * FUNCTION
- *  vector float _acoshf4(vector float x)
- *
- * DESCRIPTION
- *  The acoshf4 function returns a vector containing the hyperbolic
- *  arccosines of the corresponding elements of the input vector.
- *
- *  We are using the formula:
- *    acosh = ln(x + sqrt(x^2 - 1))
- *
- *  For x near one, we use the Taylor series:
- *
- *                infinity
- *                 ------
- *                  -   '        
- *                   -                 k
- *    acosh x =       -      C  (x - 1)
- *                   -        k
- *                  -   ,
- *                 ------
- *                 k = 0
- *
- *
- *  Special Cases:
- *	- acosh(1)        = +0
- *	- NaNs and Infinity aren't supported for single-precision on SPU.

- * FUNCTION
- *	vector double _asind2(vector double x)
- *
- * DESCRIPTION
- * 	Compute the arc sine of the vector of double precision elements 
- * 	specified by x, returning the resulting angles in radians. The input
- *      elements are to be in the closed interval [-1, 1]. Values outside 
- *      this range result in a invalid operation execption being latched in 
- *	the FPSCR register and a NAN is returned.
- *
- * 	The basic algorithm computes the arc sine using a rational polynomial
- * 	of the form x + x^3 * P(x^2) / Q(x^2) for inputs |x| in the interval 
- *      [0, 0.5]. Values outsize this range are transformed as by:
- * 
- * 	asin(x) =  PI/2 - 2*asin(sqrt((1-x)/2)) for x in the range (0.5, 1.0]
- * 
- * 	asin(x) = -PI/2 + 2*asin(sqrt((1+x)/2)) for x in the range [-1.0, -0.5)
- *
- * 	This yields the basic algorithm of:
- *
- *	   absx = (x < 0.0) ? -x : x;
- *	 
- *	   if (absx > 0.5) {
- *	     if (x < 0) {
- *	       addend = -SM_PI_2;
- *	       multiplier = -2.0;
- *	     } else {
- *	       addend = SM_PI_2;
- *	       multiplier = 2.0;
- *	     }
- *	
- *	     x = sqrt(-0.5 * absx + 0.5);
- *	   } else {
- *	     addend = 0.0;
- *	     multiplier = 1.0;
- *	   }
- *	
- *	    x2 = x * x;
- *	    x3 = x2 * x;
- *
- *	    p = ((((P5 * x2 + P4)*x2 + P3)*x2 + P2)*x2 + P1)*x2 + P0;
- *	 
- *	    q = ((((Q5 * x2 + Q4)*x2 + Q3)*x2 + Q2)*x2 + Q1)*x2 + Q0;;
- *	
- *	    pq = p / q;
- *	
- *	    result = addend - (x3*pq + x)*multiplier;
- *
- *	 Where P5-P0 and Q5-Q0 are the polynomial coeficients.

- * FUNCTION
- *  vector double _asinhd2(vector double x)
- *
- * DESCRIPTION
- *  The asinhd2 function returns a vector containing the hyperbolic
- *  arcsines of the corresponding elements of the input vector.
- *
- *  We are using the formula:
- *    asinh = ln(|x| + sqrt(x^2 + 1))
- *  and the anti-symmetry of asinh.
- *
- *  For x near zero, we use the Taylor series:
- *
- *                infinity
- *                 ------
- *                  -   '  P  (0)
- *                   -      k-1    k
- *    asinh x =       -    -----  x
- *                   -       k
- *                  -   ,
- *                 ------
- *                 k = 1
- *
- *  Special Cases:
- *    asinh(+0)        returns +0
- *    asinh(-0)        returns -0
- *    asinh(+infinity) returns +infinity
- *    asinh(-infinity) returns -infinity
- *    asinh(NaN)       returns NaN

- * FUNCTION
- *  vector float _asinhf4(vector float x)
- *
- * DESCRIPTION
- *  The asinhf4 function returns a vector containing the hyperbolic
- *  arcsines of the corresponding elements of the input vector.
- *
- *  We are using the formula:
- *    asinh = ln(|x| + sqrt(x^2 + 1))
- *  and the anti-symmetry of asinh.
- *
- *  For x near zero, we use the Taylor series:
- *
- *                infinity
- *                 ------
- *                  -   '  P  (0)
- *                   -      k-1    k
- *    asinh x =       -    -----  x
- *                   -       k
- *                  -   ,
- *                 ------
- *                 k = 1
- *
- *  Special Cases:
- *   - asinh(+0)        returns +0
- *   - asinh(-0)        returns -0
- *   - Normally,  asinh(+/- infinity) returns +/- infinity,
- *	   but on the SPU, single-precision infinity is not supported,
- *	   so it is treated as a normal number here.

- * DESCRIPTION
- *  The atan2d2 function returns a vector containing the angles

- *  input vectors.
- *
- *  The reason this function exists is to use the signs of the
- *  arguments to determine the quadrant of the result. Consider
- *  sin(x)/cos(x) on the domain (-pi, pi]. Four quadrants are
- *  defined by the signs of sin and cos on this domain.
- *
- *  Special Cases:
- *	- If the corresponding elements of x and y are zero, the 
- *    resulting element is undefined.

- * DESCRIPTION
- *  The atan2f4 function returns a vector containing the angles
- *  whose tangets are y/x for the corresponding elements of the
- *  input vectors.
- *
- *  The reason this function exists is to use the signs of the
- *  arguments to determine the quadrant of the result. Consider
- *  sin(x)/cos(x) on the domain (-pi, pi]. Four quadrants are
- *  defined by the signs of sin and cos on this domain.
- *
- *  Special Cases:
- *	- If the corresponding elements of x and y are zero, the 
- *    resulting element is undefined.

- * FUNCTION
- *  vector double _atanhd2(vector double x)
- *
- * DESCRIPTION
- *  The atanhd2 function returns a vector containing the hyperbolic
- *  arctangents of the corresponding elements of the input vector.
- *
- *  We are using the formula:
- *    atanh x = 1/2 * ln((1 + x)/(1 - x)) = 1/2 * [ln(1+x) - ln(1-x)]
- *  and the anti-symmetry of atanh.
- *
- *  For x near 0, we use the Taylor series:
- *    atanh x = x + x^3/3 + x^5/5 + x^7/7 + x^9/9 + ...
- *
- *  Special Cases:
- *  - atanh(1)  =  Infinity
- *  - atanh(-1) = -Infinity
- *  - atanh(x) for |x| > 1 = NaN
- *

- * FUNCTION
- *  vector float _atanhf4(vector float x)
- *
- * DESCRIPTION
- *  The atanhf4 function returns a vector containing the hyperbolic
- *  arctangents of the corresponding elements of the input vector.
- *
- *  We are using the formula:
- *    atanh x = 1/2 * ln((1 + x)/(1 - x)) = 1/2 * [ln(1+x) - ln(1-x)]
- *  and the anti-symmetry of atanh.
- *
- *  For x near 0, we use the Taylor series:
- *    atanh x = x + x^3/3 + x^5/5 + x^7/7 + x^9/9 + ...
- *
- *  Special Cases:
- *  - atanh(1)  =  HUGE_VALF
- *  - atanh(-1) = -HUGE_VALF
- *	- The result is undefined for x outside of the domain [-1,1],
- *	  since single-precision NaN is not supported on the SPU.
- *

- *	ceiling function are provided - full range and limited (integer)
- *	range.
- *
- *	The full range form (default) provides ceiling computation on
- *	all IEEE floating point values. The ceiling of NANs remain NANs.
- *	The ceiling of denorms results in zero.
- *
- *	The limited range form (selected by defining CEIL_INTEGER_RANGE)
- *	compute ths ceiling of all floating-point values in the 32-bit
- *	signed integer range. Values outside this range get clamped.

- * FUNCTION
- *  vector double _erfcd2(vector double x)
- *
- * DESCRIPTION
- *  The erfcd2 function computes the complement error function of each element of x.
- *
- *  Accuracy Note: We would benefit from a rational approximation in the domain
- *  1.2 < x < 2.0 and also around x = 2.5.
- *
- *  C99 Special Cases:
- *  - erfc(+0) returns +1
- *  - erfc(-0) returns +1
- *  - erfc(+infinite) returns +0
- *  - erfc(-infinite) returns +2
- *
- *  Other Cases:
- *  - erfc(Nan) returns Nan

- * FUNCTION
- *	vector double _expd2(vector double x)
- *
- * DESCRIPTION
- *	_expd2 computes e raised to the input x for
- *	each of the element of the double word vector.
- *
- * Calculation is performed by reducing the input argument
- * to within a managable range, and then computing the power
- * series to the 11th degree.
- *
- * Range reduction is performed using the property:
- *
- *	exp(x) = 2^n * exp(r)
- *
- * Values for "n" and "r" are determined such that:
- *
- *       x = n * ln(2) + r, |r| <= ln(2)/2
- *
- *       n = floor(  (x/ln(2)) + 1/2  )
- *       r = x - (n * ln(2))
- *
- * To enhance the precision for "r", computation is performed
- * using a two part representation of ln(2). 
- *
- * Once the input is reduced, the power series is computed:
- *
- *                    __12_
- *                    \
- *       exp(x) = 1 +  \   (x^i)/i!
- *                     /
- *                    /____
- *                     i=2
- *
- * The resulting value is scaled by 2^n and returned.

- * FUNCTION
- *       vector double hypotd2(vector double x, vector double y)
- *
- * DESCRIPTION
- *     The function hypotd2 returns a double vector in which each element is 
- *     the square root of the sum of the squares of the corresponding 
- *     elements of x and y. 
- *  
- *     The purpose of this function is to avoid overflow during
- *     intermediate calculations, and therefore it is slower than 
- *     simply calcualting sqrt(x^2 + y^2).
- *  
- *     This function is performed by factoring out the larger of the 2
- *     input exponents and moving this factor outside of the sqrt calculation.
- *     This will minimize the possibility of over/underflow when the square
- *     of the values are calculated. Think of it as normalizing the larger
- *     input to the range [1,2).
- *
- *  Special Cases:
- *	- hypot(x, +/-0)              returns |x|
- *	- hypot(+/- infinity, y)      returns +infinity
- *	- hypot(+/- infinity, NaN)    returns +infinity

- * FUNCTION
- *  vector float _hypotf4(vector float x, vector float y)
- *
- * DESCRIPTION
- *     The function hypotf4 returns a float vector in which each element is 
- *     the square root of the sum of the squares of the corresponding 
- *     elements of x and y. In other words, each element is sqrt(x^2 + y^2).
- *
- *     The purpose of this function is to avoid overflow during
- *     intermediate calculations, and therefore it is slower than 
- *     simply calcualting sqrt(x^2 + y^2).
- *  
- *     This function is performed by factoring out the larger of the 2
- *     input exponents and moving this factor outside of the sqrt calculation.
- *     This will minimize the possibility of over/underflow when the square
- *     of the values are calculated. Think of it as normalizing the larger
- *     input to the range [1,2).
- *
- *
- *  Special Cases:
- *	- hypot(x, +/-0)              returns |x|
- *	- hypot(+/- infinity, y)      returns +infinity
- *	- hypot(+/- infinity, NaN)    returns +infinity

- * FUNCTION
- *	vector float _scalbnf4(vector float x, vector signed int exp)
- *
- * DESCRIPTION
- *      The _scalbnf4 function returns a vector containing each element of x 
- *      multiplied by 2^n computed efficiently.  This function is computed 
- *      without the assistance of any floating point operations and as such 
- *      does not set any floating point exceptions.
- *
- *      Special Cases:
- *	  - if the exponent is 0, then x is either 0 or a subnormal, and the 
- *          result will be returned as 0.
- *        - if the result if underflows, it will be returned as 0.
- *        - if the result overflows, it will be returned as FLT_MAX.

- *
- *      Special Cases:
- *	  - if the exponent is 0, then x is either 0 or a subnormal, and the
- *          result will be returned as 0.
- *        - if the result if underflows, it will be returned as 0.
- *        - if the result overflows, it will be returned as FLT_MAX.

- * FUNCTION
- *	vector unsigned long long _signbitd2(vector double x)
- *
- * DESCRIPTION
- *      The signbitd2 function returns a vector which contains either all ones 
- *      or all zeros, depending on the sign of the corresponding input vector 
- *      element.
- *
- *      Note that the signbit functions are not logically equivalent to 
- *      x < 0.0.  IEEE 754 floating point rules include a signed zero, so if
- *      the input value is –0.0, signbit will return non-zero, but the naive
- *      implementation will not.
- * 
- * RETURNS
- *      The function signbitf4 returns an unsigned int vector in which each
- *      element is defined as:
- *
- *        - ULLONG_MAX (0xFFFFFFFFFFFFFFFF)   if the sign bit is set for the 
- *                                            corresponding element of x
- *        - 0          (0x0000000000000000)   otherwise.

- * FUNCTION
- *	vector double _tgammad2(vector double x)
- *
- * DESCRIPTION
- *	_tgammad2 
- *
- *	This is an interesting function to approximate fast
- *	and accurately. We take a fairly standard approach - break 
- *	the domain into 5 separate regions:
- *
- *	1. [-infinity, 0)  - use 
- *	2. [0, 1)          - push x into [1,2), then adjust the 
- *	                     result.
- *	3. [1, 2)          - use a rational approximation.
- *	4. [2, 10)         - pull back into [1, 2), then adjust
- *	                     the result.
- *	5. [10, +infinity] - use Stirling's Approximation.
- *
- *
- * Special Cases:
- *	- tgamma(+/- 0) returns +/- infinity
- *	- tgamma(negative integer) returns NaN
- *	- tgamma(-infinity) returns NaN
- *	- tgamma(infinity) returns infinity
- *

- * FUNCTION
- *  vector float _tgammaf4(vector float x)
- *
- * DESCRIPTION
- *  The tgammaf4 function returns a vector containing tgamma for each 
- *  element of x 
- *
- *	We take a fairly standard approach - break the domain into 5 separate regions:
- *
- *	1. [-infinity, 0)  - use gamma(x) = pi/(x*gamma(-x)*sin(x*pi))
- *	2. [0, 1)          - push x into [1,2), then adjust the 
- *	                     result.
- *	3. [1, 2)          - use a rational approximation.
- *	4. [2, 10)         - pull back into [1, 2), then adjust
- *	                     the result.
- *	5. [10, +infinity] - use Stirling's Approximation.
- *
- *
- * Special Cases:
- *	- tgamma(+/- 0) returns +/- infinity
- *	- tgamma(negative integer) returns NaN
- *	- tgamma(-infinity) returns NaN
- *	- tgamma(infinity) returns infinity
- *
