NAME    [Toc]    [Back]

     cosh, coshf - hyperbolic cosine functions

SYNOPSIS    [Toc]    [Back]

     #include <math.h>

     double
     cosh(double x);

     float
     coshf(float x);

DESCRIPTION    [Toc]    [Back]

     The cosh() function computes the  hyperbolic  cosine  of  x.
The coshf()
     function is a single precision version of cosh().

RETURN VALUES    [Toc]    [Back]

     If the magnitude of x is too large, cosh(x) and coshf(x) return Inf and
     set the global variable errno to ERANGE.
