Note that in Cowlishaw's implementation of decimal numbers, decimals are *not* exact. Truncation (rounding), overflow, and underflow errors can occur under addition, subtraction, and multiplication. It's trivial to set them to be unbounded, but then Cowlishaw provides no mechanism for determining the truncation of division. -- --- Aahz (@pobox.com) Hugs and backrubs -- I break Rule 6 <*> http://www.rahul.net/aahz/ Androgynous poly kinky vanilla queer het Pythonista I don't really mind a person having the last whine, but I do mind someone else having the last self-righteous whine.
