Example
The following program utilizes the “double” functions (explained on
pages 52-55) to multiply large numbers of any base and obtain an
exact decimal answer up to 39 digits long (that is, up to and not
including 10'® x 254). The double-sized result is placed into regis-
ters X (the most significant digits) and Y (the 19 least significant
digits).
Since the “double” functions operate internally in binary, it is nec-
essary to perform the extra manipulations below (dividing by 10'°,
the largest exponent of 10 that can be held in one register) to obtain
a meaningful decimal answer.
