In search of a module ...

[David Cantrell]

Do any of you know of a module that implements 2s-complement arithmetic
on fixed-size integers?

I realise that on any sane machine (maybe even on every machine perl
runs on) the underlying signed ints are 2s-complement, but I need to do
2s-complement mathemagics on perl scalars, not C ints.
