Should Fraction be stored as a mixed number?

[LemmaEOF]

Not much else to say, really. We're just deciding whether to:

• store just long numerator and long denominator as we are right now
• store int whole, int numerator, and int denominator
• store int whole, long numerator, and long denominator

I don’t really have a preference, would go for one that can be optimised to be faster though.

I think 3 ints should be enough. With wholes split off numerators should never be too high.

[LemmaEOF]

yeah, and though Alex did worry that LCMs might get too big for an int, that's why we simplify on every op. The worst LCM I can think of reasonably happening is 81,000 (LCM of 1,000 and 81, which is also a multiple of 3, 4, 5, 6, 8, 9, 10, 12, and most other common units folks would want).

Sounds good to me too. At least have the person who makes the changes document all the decisions.

should whole be stored as a long/biginteger so that it can store more fluid?
