    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 || _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.
