-FUNCTION
-        <<acos>>, <<acosf>>---arc cosine
-
-INDEX
-	acos
-INDEX
-	acosf
-
-ANSI_SYNOPSIS
-        #include <math.h>
-        double acos(double <[x]>);
-        float acosf(float <[x]>);
-
-TRAD_SYNOPSIS
-        #include <math.h>
-        double acos(<[x]>)
-        double <[x]>;
-
-        float acosf(<[x]>)
-        float <[x]>;

-DESCRIPTION
-
-	<<acos>> computes the inverse cosine (arc cosine) of the input value.
-	Arguments to <<acos>> must be in the range @minus{}1 to 1. 
-
-	<<acosf>> is identical to <<acos>>, except that it performs
-	its calculations on <<floats>>.
-
-RETURNS
-	@ifnottex
-	<<acos>> and <<acosf>> return values in radians, in the range of 0 to pi.
-	@end ifnottex
-	@tex
-	<<acos>> and <<acosf>> return values in radians, in the range of <<0>> to $\pi$.
-	@end tex
-
-	If <[x]> is not between @minus{}1 and 1, the returned value is NaN
-	(not a number) the global variable <<errno>> is set to <<EDOM>>, and a
-	<<DOMAIN error>> message is sent as standard error output.
-
-	You can modify error handling for these functions using <<matherr>>.
