TANH(3F)                COMMAND REFERENCE                TANH(3F)



NAME
     tanh, dtanh - FORTRAN hyperbolic tangent intrinsic function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2

     r2 = tanh(r1)

     dp2 = dtanh(dp1)
     dp2 = tanh(dp1)

DESCRIPTION
     Tanh returns the real hyperbolic tangent of its real
     argument.  Dtanh returns the double-precision hyperbolic
     tangent of its double precision argument.  The generic form
     tanh may be used to return a double-precision value given a
     double-precision argument.
