NAME
     cosh, coshf -- hyperbolic cosine function

LIBRARY
     Math Library (libm, -lm)

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.
