Base Conversions and Arithmetic and Logic
11-5
The result of an operation is always an integer (any fractional portion is
truncated).
Whereas conversions change only the display of the number but not the actual
number in the X–register, arithmetic does alter the number in the X–register.
If the result of an operation cannot be represented in valid 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:
