cosh(3F)                                                 cosh(3F)



     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.
