Guardian Native C Library Calls (a - e) casinl(3)
NAME
casinl - Computes the long double complex arc sine
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zcredll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/ycredll
SYNOPSIS
#include <complex.h>
long double complex casinl(
long double complex z);
PARAMETERS
z Specifies a long double complex value.
DESCRIPTION
The casinl() function is a long double complex version of the casin() function; it takes a long
double complex argument and returns a long double complex result.
The casinl() function computes the complex arc sine of z, with branch cuts outside the interval
[-1,+1] along the real axis.
NOTES
This function is implemented only for the IEEE_float floating-point option. Applications using
this function cannot be compiled if the specified floating-point option is Tandem_float.
RETURN VALUES
The casinl() function returns the complex arc sine of z in the range of a strip mathematically
unbound along the imaginary axis and in the interval [-π/2, +π/2] along the real axis.
ERRORS
No errors are defined.
RELATED INFORMATION
Functions: asin(3), asinh(3), casin(3), casinf(3), csin(3).
STANDARDS CONFORMANCE
This function conforms to the ISO/IEC 9899:1999 standard.
This function conforms to the IEEE Std 1003.1, 2004 Edition.
