COSH(3)                 NetBSD Library Functions Manual                COSH(3)


NAME

     cosh, coshf, coshl, -- hyperbolic cosine function


LIBRARY

     Math Library (libm, -lm)


SYNOPSIS

     #include <math.h>

     double
     cosh(double x);

     float
     coshf(float x);

     long double
     coshl(long double x);


DESCRIPTION

     The cosh(), coshf() and coshl() 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.


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 X3.159-1989 (``ANSI C89'').
