I think of writing Saturn code in a similar fashion to building furniture out of Lego blocks. It can be done, but you better have both a good reason and a good plan or you'll go insane before you finish it.

Although I rarely choose assembly solutions as a first approach, this one seemed like a perfect fit -- simply setting the exponent and sign fields to 0 was all that was needed, and I knew that would be fairly easy (and fast) in assembly.

I agree!
