COSH(3F-SysV)       RISC/os Reference Manual        COSH(3F-SysV)



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 argu-
     ment.  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.
