Syntax

TANH(argument)

specifies a numeric constant, variable, or expression.

The TANH function returns the hyperbolic tangent of the argument, which is given by

\begin{matrix} \frac{(ε^{a r g u m e n t} - ε^{- a r g u m e n t})}{(ε^{a r g u m e n t} + ε^{- a r g u m e n t})} \end{matrix}

The following SAS statements produce these results.
