Summary
Returns a (real) number whose value is equal to the hyperbolic tangent of the parameter's numeric value.
Syntax
TANH(X : Number / Numeric_String) : Number
Example Usage
TANH(TextWidth / TextHeight) < 0.17
Returns objects for which the hyperbolic tangent of the ratio of their TextWidth distance to their TextHeight distance is less than 0.17. (That is equivalent to returning objects for which the ratio of their TextWidth distance to their TextHeight distance is less than 0.1717).
(TextWidth / TextHeight) >= TANH(0.2)
Returns objects for which the ratio of their TextWidth distance to their TextHeight distance is equal to, or greater than, the hyperbolic tangent of 0.2 (which is 0.1974).
