When X0.0 is ON, the hyperbolic tangent of the binary floating-point
number in (D1, D0) is stored in (D11, D10).

If the absolute value of a conversion result is greater than the maximum
floating-point value available, a carry flag will be ON.

If the absolute value of a conversion reuslt is less than the minimum
floating-point value available, a borrow flag will be ON.

If a converseion result is 0, a zero flag will be ON.

SM1064 is the zero flag in an Ox motion subroutine, and SM968 is the
zero flag in O100.

SM1065 is the borrow flag in an Ox motion subroutine, and SM969 is
the borrow flag in O100.

SM1066 is the carry flag in an Ox motion subroutine, and SM970 is the
carry flag in O100.
