I want to multiply two numbers, and detect if there was an overflow. What is the simplest way to do that?

We have 2's complement for integers that allows us to perform operations without worrying about the sign. That is a big help at the implementation level. Similarly we have so many floating point operations and yet we rely on sign and magnitude. What is the reason? Why can't a 2's complement like… >>> More
