Details

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

$table with 1 row and 1 column , row1 column 1 , fraction e super eh r g u m e n t end super . minus . e super negative eh r g u m e n t end super , over e super eh r g u m e n t end super . plus . e super negative eh r g u m e n t end super end fraction , end table$

Example

The following statements are examples of the TANH function:

Statements	Results
x=tanh(0);	0
x=tanh(0.5);	0.46211715726
select tanh(-0.5);	-0.46212
