If someone was proposing Fractions everywhere -- there would be massive performance and backward compatibility issues -- but yes, Error Analysis would be a lot easier :-) Anyway, it looks like this was always about (or was transformed into) an idea to better support symbolic math, which is in a new thread now. -CHB Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
