NAME
asinh, asinhf, asinhl  inverse hyperbolic sine function
SYNOPSIS
#include <math.h>
double asinh(double x);
float asinhf(float x);
long double asinhl(long double x);
Link with lm.
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
asinh():

_BSD_SOURCE  _SVID_SOURCE  _XOPEN_SOURCE >= 500 
_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED  _ISOC99_SOURCE 
_POSIX_C_SOURCE >= 200112L;
or

asinhf(),
asinhl():

_BSD_SOURCE  _SVID_SOURCE  _XOPEN_SOURCE >= 600  _ISOC99_SOURCE 
_POSIX_C_SOURCE >= 200112L;
or
cc std=c99
DESCRIPTION
The
asinh()
function calculates the inverse hyperbolic sine of
x;
that is the value whose hyperbolic sine is
x.
RETURN VALUE
On success, these functions return the inverse hyperbolic sine of
x.
If
x
is a NaN, a NaN is returned.
If
x
is +0 (0), +0 (0) is returned.
If
x
is positive infinity (negative infinity),
positive infinity (negative infinity) is returned.
ERRORS
No errors occur.
CONFORMING TO
C99, POSIX.12001.
The variant returning
double
also conforms to
SVr4, 4.3BSD, C89.
