COSH(3)			    BSD Programmer's Manual		       COSH(3)

NAME
     cosh, coshf - hyperbolic cosine functions

SYNOPSIS
     #include <math.h>

     double
     cosh(double x);

     float
     coshf(float x);

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

ERRORS
     If the result would overflow, then:

     _IEEE_    The return value is +Inf.
     _POSIX_   Same as _IEEE_, but errno is also set to ERANGE.
     _XOPEN_   Same as _POSIX_, but errno is only set if matherr(3) returns 0.
	       The exception type is DOMAIN.
     _SVID_    Same as _XOPEN_, but the return value is MAXFLOAT.

SEE ALSO
     acos(3),  asin(3),	 atan(3),  atan2(3),  cos(3),  math(3),	 sin(3),
     sinh(3),  tan(3),	tanh(3)

STANDARDS
     The cosh() function conforms to ANSI C X3.159-1989 (``ANSI C '').
