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.
If the result of an operation cannot be represented in 36 bits, the display
shows
# $
and then shows the largest positive or negative number
possible.
Example:
Here are some examples of arithmetic in Hexadecimal, Octal, and Binary
modes:
