People who use GMP every day might surprise you <wink>.

There should be a standard Decimal type in 2.4, but there won't be a C
interface at first (it's pure Python code -- in Python CVS
sandbox/decimal/).  mxNumber isn't the same thing, but I've enjoyed
using it since you first released it.  Thanks for doing it!
