Naturally, there's also the option of splitting N1 and N2 up into

combining the results of said multiplies. That looks like it'd be a
pain to code, so
I am going to try the other algorithm first. Depending on how fast it
is, I
may or may not want to give "7-char chunks" a try as well.
I have experimented with this and like it better than the ASCII
approach. However, if speed is not an issue, then the ASCII approach
may be easier.
Folks have given a lot of thought to multiplication and division, so it
might be good to stand on their shoulders.
You might want to consider DC and shell, if speed is not important.
When I get back into this, I will likely go with Victor's suggestion
and go with a well-established C library (or build my own) and make an
external. I want interval arithmetic, too, so I might have to build my
own.
I've considered making a general number that would encompass all that
but I'm not sure what to do with very small numbers. Floating point
would handle those, so I might have to go that way: indefinite
precision decimal floating point interval with small vectors.
