I sent it to Phil Nelson [in August], but I probably insulted him with the condition it is in (you need to manually change the make files to include libgmp). On this vein, why doesn't GMP include a fixed-point data type (either decimal or binary)? Is it too trivial for y'all to bother with? It would be handy for currency calculations, like the cost of a loaf of bread in drachmas.

Fixed point is what people use because their platform doesn't support
floating point because it sucks. You can approximate fixed point using
mpq and always using a denominator that's a power of ten.
