ATANH

This function calculates the inverse hyperbolic tangent of a number.

Syntax

ATANH(value)

Arguments

[Required] 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.

Examples

ATANH(B5)

ATANH(R5C2)

ATANH(0.55) gives the result 0.6183813136

ATANH(-0.2) gives the result -0.2027325541
