Allows a larger possible
answer since there is no
sign bit.
Double-multiplies the
contents of the X-and Y-
registers.
Stores the most
significant digits of the
result into R,.
Stores the least
significant digits of the
result into R,.
Recalls (for the divisor)
the largest possible
powerof 10.
Ninteen least signifi-
cant digits of product.
Most significant digits.
Divisor.
Ensures that the result is
expressed in base 10.
To run the program, set the word size to 64 and store 10'? (the
largest possible power of 10 in Unsigned mode) into R(. Then enter
the numbers 12345678987654 and 987654321234567 into the X- and
Y-registers.
