TANH(3F)                             SysV                             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.
