TANH (Number) TANH (Number)
Number
Number Number
The input number.
Returns
Number Number
The hyperbolic tangent.
Returns the hyperbolic tangent of a number. The result is always strictly between -1 and 1. The hyperbolic tangent is equivalent to SINH (Number) / COSH (Number) SINH (Number) / COSH (Number). The inverse of this function is ATANH.
Example
TANH (0.5)
TANH (0,5)
Returns roughly 0.4621.
