Arithmetic in Bases 2, 8, and 16

. However, you should realize that most
operations other than arithmetic will not produce meaningful results since the
fractional parts of numbers are truncated.
Arithmetic in bases 2, 8, and 16 is in 2's complement form and uses integers only:
If a number has a fractional part, only the integer part is used for an
arithmetic calculation.
The result of an operation is always an integer (any fractional portion is
truncated).
Whereas conversions change only the displayed number and not the number in
the X–register,
arithmetic does alter the number in the X–register.
