ASINH(3)                                                                Linux Programmer's Manual                                                               ASINH(3)

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 <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

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

DESCRIPTION
       These functions calculate 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.
