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(): _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 500 || /* Since glibc 2.19: */ _DEFAULT_SOURCE || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE asinhf(), asinhl(): _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L || /* Since glibc 2.19: */ _DEFAULT_SOURCE || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

DESCRIPTION

These functions calculate the inverse hyperbolic sine of x; that is the value whose hyper‐ bolic 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.
