NAME

cosh, dcosh − Fortran hyperbolic cosine intrinsic function

SYNOPSIS

real r1, r2
double precision dp1, dp2

r2 = cosh(r1)

dp2 = dcosh(dp1)
dp2 = cosh(dp1)

DESCRIPTION

cosh returns the real hyperbolic cosine of its real argument.  dcosh returns the double-precision hyperbolic cosine of its double-precision argument.  The generic form cosh may be used to return the hyperbolic cosine in the type of its argument.
