cosh(3F)

NAME
     cosh, dcosh, qcosh - FORTRAN hyperbolic cosine intrinsic function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     real*16 qp1, qp2

     r2 = cosh(r1)

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

     qp2 = qcosh(qp1)
     qp2 = cosh(qp1)

DESCRIPTION
     cosh returns the real hyperbolic cosine of its real argument, dcosh
     returns the double-precision hyperbolic cosine of its double-precision
     argument, and qcosh returns the real*16 hyperbolic cosine of its real*16
     argument.  The generic form cosh may be used to return a double-precision
     value when given a double-precision argument, or a real*16 value when
     given a real*16 argument.
