TANH
Applies to: 
Calculated column
Calculated table
Measure
Visual calculation
Returns the hyperbolic tangent of a number.
Syntax
TANH(number)
Parameters
| Term | Definition |
|---|---|
| number | Required. Any real number. |
Return value
Returns the hyperbolic tangent of a number.
Remarks
The formula for the hyperbolic tangent is:
$$\text{TANH}(z) = \frac{\text{SINH}(z)}{\text{COSH}(z)}$$
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
