Arc Tangent Hyperbolic (ATANH)

Built-in number for ATANH is 410.
ATANH (
       source   : binary floating-point(8) value
) :   binary floating-point(8) value which is the arc tangent hyperbolic of the
      source value

Description:   The inverse of the tangent hyperbolic of the numeric value of the source operand is computed and the result (in radians) is returned.

The result is in the range:

-infinity <= ATANH(source) <= +infinity

See floating point results from special values for additional information.
