ATANH Function

Purpose

Returns the hyperbolic arc tangent of an arithmetic expression.

Syntax

ATANH(x)

Parameters

x is a floating-point value such that -1 < x < 1.

Description

The ATANH(x) function returns the hyperbolic arc tangent of x. The result has the same data type as x.

Examples

ATANH(0.5)   /* returns 0.54930 */

Restrictions

An ATANH operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers.
