NAME
casinh - Computes the complex arc hyperbolic sine
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL

SYNOPSIS
#include <complex.h>
double complex casinh(
double complex z);
PARAMETERS
z Specifies a double complex value.
DESCRIPTION
The casinh() function computes the complex arc hyperbolic sine of z, with branch cuts outside
the interval [-i, +i] along the imaginary 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 casinh() function returns the complex arc hyperbolic sine of z in the range of a strip
mathematically unbound along the real axis and in the interval [-iπ/2, +iπ/2] along the imaginary
axis.
ERRORS
No errors are defined.
RELATED INFORMATION
Functions: casinhf(3), casinhl(3), csinh(3).
STANDARDS CONFORMANCE
This function conforms to the ISO/IEC 9899:1999 standard.
This function conforms to the IEEE Std 1003.1, 2004 Edition.
