tanh(3f)
NAME
tanh, dtanh − Fortran hyperbolic tangent intrinsic function
SYNTAX
real r1, r2
double precision dp1, dp2
r2 = tanh(r1)
dp2 = dtanh(dp1)
dp2 = tanh(dp1)
DESCRIPTION
The tanh function returns the real hyperbolic tangent of its real argument. The dtanh function 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.
