     asinh(double x);

     asinhf(float x);

DESCRIPTION    [Toc]    [Back]

     The asinh() and the asinhf() functions compute the inverse hyperbolic
     sine of the real argument x.  For a discussion of error due to roundoff,
     see math(3).

RETURN VALUES    [Toc]    [Back]

     The asinh() and the asinhf() functions return the inverse hyperbolic sine
     of x.
