Improved method that handles multiplication by the minimum negative number |
||
Line 31:
Please correct me if I'm wrong, but I think that there should be -4 × 3 instead of -6 × 2. Because 0011 is 3 (and 1101 is -3 in two's complement notation) and 1100 is -4 in two's complement notation. Of course, the product is the same.

== Improved method that handles multiplication by the minimum negative number ==
The described method in the article can't handle multiplications like -128 x 1 (when using 8 bits). The problem arises from the fact that -128 is the minimum negative number when using 8 bits for representation. I have made a minor modification in the method and added one more example to show the improved technique. Hope that everything is OK.
