NAME

     cosh, coshf - hyperbolic cosine function

LIBRARY

     libm

SYNOPSIS

     #include <math.h>

     double
     cosh(double x);

     float
     coshf(float x);

DESCRIPTION

     The cosh() and coshf() functions compute the hyperbolic cosine of x.

RETURN VALUES

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