Tanh function in Seeq

[Teddy]

A user recently asked "How do I implement a hyperbolic tangent function in Seeq?"

[Teddy]

Unfortunately, Seeq does not support the hyperbolic tangent function directly. However, it does support the exponential function so re-creating the hyperbolic tangent function is fairly simple.  The formula below can be used to achieve the same result as a tanh or hyperbolic tangent. 

(Constant.E ^ (2*$x )- 1)/(Constant.E ^(2*$x) + 1)

Note: To create and exponent in Seeq (e^x) you need to use Constant.E^x.
