-FUNCTION
- <<asin>>, <<asinf>>---arc sine
-
-INDEX
- asin
-INDEX
- asinf
-
-ANSI_SYNOPSIS
- #include <math.h>
- double asin(double <[x]>);
- float asinf(float <[x]>);
-
-TRAD_SYNOPSIS
- #include <math.h>
- double asin(<[x]>)
- double <[x]>;
-
- float asinf(<[x]>)
- float <[x]>;
-
-
-DESCRIPTION
-
-<<asin>> computes the inverse sine (arc sine) of the argument <[x]>.
-Arguments to <<asin>> must be in the range @minus{}1 to 1.
-
-<<asinf>> is identical to <<asin>>, other than taking and
-returning floats.
-
-You can modify error handling for these routines using <<matherr>>.
-
-RETURNS
-@ifinfo
-<<asin>> returns values in radians, in the range of -pi/2 to pi/2.
-@end ifinfo
-@tex
-<<asin>> returns values in radians, in the range of $-\pi/2$ to $\pi/2$.
-@end tex
-
-If <[x]> is not in the range @minus{}1 to 1, <<asin>> and <<asinf>>
-return NaN (not a number), set the global variable <<errno>> to
-<<EDOM>>, and issue a <<DOMAIN error>> message.
-
-You can change this error treatment using <<matherr>>.
