This function calculates the inverse hyperbolic tangent of a number.

Syntax

ATANH(value)

Arguments

For the argument, you can specify any real number between 1 and –1, excluding –1 and 1.

Remarks

This function is the inverse of the hyperbolic tangent, so ATANH(TANH(n)) gives the result n.

Data Types

Accepts numeric data. Returns numeric data.

Examples

ATANH(B5)

ATANH(R5C2)

ATANH(0.55) gives the resultlt 0.6183813136

ATANH(-0.2) gives the result -0.2027325541
