COSH(3)                 System Library Functions Manual                COSH(3)

NAME
     cosh, coshf - hyperbolic cosine functions

SYNOPSIS
     #include 

     double
     cosh(double x);

     float
     coshf(float x);

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

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