I don't understand what you mean by "error analysis", unless you're referring to performance degradation due to Fraction propagation.
The error analysis for arithmetic with Fraction is much easier than for float:
sure -- but the error analysis is harder for computations that use a mixture of Fraction and float, and it's not obvious where which is used. 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
