Description: Converts the source operand to extended precision (if necessary) and
Operation Table:
Floating-Point Status Register:
5-20
calculates the hyperbolic arc tangent of that value. Stores the result in the destination
floating-point data register. This function is not defined for source operands outside of
the range ( – 1... + 1); and the result is equal to – infinity or + infinity if the source is
equal to + 1 or – 1, respectively. If the source is outside of the range [ – 1... + 1], a NAN
is returned as the result, and the OPERR bit is set in the floating-point status register.

Quotient Byte:
NOTES:
1. If the source operand is a NAN, refer to 1.6.5 Not-A-Numbers for more information.
2. Sets the OPERR bit in the floating-point status register exception byte.
