TANH

TANH is a DAX function that returns the hyperbolic tangent of a number.

Syntax

TANH( Number )

Argument	Properties	Description
Number		Any real number.

Return Values

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.

Formula	Description	Result
= TANH(-2)	Hyperbolic tangent of -2 (-0.96403)	-0.964028
= TANH(0)	Hyperbolic tangent of 0 (0)	0
= TANH(0.5)	Hyperbolic tangent of 0.5 (0.462117)	0.462117
