If the argument is a number, the BX register
points to the Floating-Point Accumulator
(FAC) where the argument is stored.
If the argument is an integer:
FAC-2 contains the upper 8 bits of the
argument.
FAC-3 contains the lower 8 bits of the
argument.
If the argument is a single precision floating-
point number:
F AC-2 contains the middle 8 bits of mantissa.
F AC-3 contains the lowest 8 bits of mantissa.
