NAME
     cosh, coshf -- hyperbolic cosine functions

LIBRARY
     Math Library (libm, -lm)

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.

RETURN VALUES
     The cosh()	and the	coshf()	functions return the hyperbolic	cosine unless
     the magnitude of x	is too large; in this event, the global	variable errno
     is	set to ERANGE.

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