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 cc -std=c99
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 (nega-
tive infinity) is returned.
ERRORS
No errors occur.
ATTRIBUTES
Multithreading (see pthreads(7))
The asinh(), asinhf(), and asinhl() functions are thread-safe.
CONFORMING TO
C99, POSIX.1-2001. The variant returning double also conforms to SVr4,
4.3BSD, C89.
