Also, an idea occurred to me while reading your comments. The current assumption is that a Number always holds a single value. How if we made it so that it held two values? They are the numerator and the denominator.

Then we'd have a rational number, instead of an arbitrary precision decimal. I think that's a sufficiently different data type that it should be a different class (if required), and probably a separate RFC, and for now it's better to stay closer to the existing BCMath API. Developers should be prepared to accept that an arbitrary precision decimal can't represent 1/3 exactly, just like a binary float can't represent 1/10 exactly.
