NAME
       asinh, asinhf, asinhl - inverse hyperbolic sine function

SYNOPSIS
       #include 

       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(), asinhf(), asinhl(): _BSD_SOURCE || _SVID_SOURCE ||
       _XOPEN_SOURCE >= 500 || _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.

CONFORMING TO
       SVr4,  POSIX.1-2001,  4.3BSD,  C89.  The float and long double variants
       are C99 requirements.
