Now, fractions are considered equal if they have the same ratio:
- 6/6 == 12/12 => True
- 3/6 == 3/12 => False
- 1/6 == 2/12 => True
It's interesting to note this implementation is actually more
numerically stable than float comparison, though that wasn't really the
goal.
The main reason for this is to allow other fields to take over when
sorting multi-field fractional data: cov (lines + branches), testmarks
(passed + time), etc. Before, sorting would usually stop after
mismatched fraction fields, which wasn't all that useful.
