asin(3M)asin(3M)NAMEasin(), asinf(), asinl(), asinw(), asinq() - arcsine functions
SYNOPSIS
HP Integrity Server Only
DESCRIPTION
returns the arcsine of x,
is a version of it takes a argument and returns a result.
Integrity Server Only
is a version of it takes a argument and returns a result.
is an version of it takes an argument and returns an result.
is equivalent to on HP-UX systems.
USAGE
To use these functions compile either with the default option or with
the and the options.
To use (for Integrity servers) or compile also with the option.
To use any of these functions, make sure your program includes and link
in the math library by specifying on the compiler or linker command
line.

PA-RISC Only
Millicode versions of the and functions are available. Millicode ver‐
sions of math library functions are usually faster than their counter‐
parts in the standard library. To use these versions, compile your
program with the or the optimization option.
For special cases, the millicode versions return the values described
in the section, but do not set
RETURN VALUE
If the magnitude of x is greater than one, returns NaN and raises the
invalid exception.
If x is NaN, returns NaN.
When it raises no other exception, whether raises the inexact exception
is unspecified.
ERRORS
If the magnitude of x is greater than one, sets to [EDOM].
Integrity Server
HP-UX functions on Integrity server do not set by default. For set‐
ting, compile with the option.
