asinh(), asinhf()

inverse hyperbolic sine function 

Function


SYNOPSIS

#include <math.h>

double asinh(double x)

float asinhf(float x)


DESCRIPTION

The asinh() and asinhf() functions compute the inverse hyperbolic sine of the real argument.

The asinhf() function is a single-precision version of asinh().


PARAMETERS

x 

Value whose inverse hyperbolic sine to compute.


RETURN VALUES

The asinh() and asinhf() functions return the inverse hyperbolic sine of x.

If x is NaN, NaN is returned. Additionally, in POSIX mode, the global variable errno is set to EDOM, and in SVID and XOPEN modes, the matherr() function is called.


CONFORMANCE

asinh(): UNIX 98

asinhf(): PTC MKS Toolkit UNIX APIs extension


MULTITHREAD SAFETY LEVEL

MT-Safe.


PORTING ISSUES

None.
