TANH(Number) Function
Calculates the hyperbolic tangent of the
argument “Number”. Returns a numeric value greater than or equal to -1 and less
than or equal to 1. It is a continuous function that can take any value, so the
argument “Number” can take any numeric value, positive, negative or zero. For
example:
=TANH(0) Returns 0.
=TANH(0,5) Returns 0,4621.
=TANH(-0,8) Returns -0,6640.
