tanh(3F)                                                 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.
