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
asinh ():
_BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 500 || _ISOC99_SOURCE; or
cc -std=c99
asinhf (),
asinhl ():
_BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; 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.1-2001.
The variant returning
double
also conforms to
SVr4, 4.3BSD, C89.
