TANH

Returns the hyperbolic tangent of the numeric value passed to this function.

Syntax

TANH( numeric_value )

The following table describes the argument for this command:

Argument	Required/ Optional	Description
numeric_value	Required	Numeric datatype. Numeric data expressed in radians (degrees multiplied by pi divided by 180). Passes the numeric values for which you want to calculate the hyperbolic tangent. You can enter any valid transformation expression.

Return Value

Double value.

NULL if a value passed to the function is NULL.

Example

The following expression returns the hyperbolic tangent for the values in the Angles port:

TANH( ANGLES )

ANGLES	RETURN VALUE
1.0	0.761594155955765
2.897	0.993926947790665
3.66	0.998676551914886
5.45	0.999963084213409
0	0.0
0.345	0.331933853503641
NULL	NULL

Tip

You can perform arithmetic on the values passed to TANH before the function calculates the hyperbolic tangent. For example:

TANH( ARCS / 360 )
