That sounds like a good argument for two ints to me.
Although you'd have
to do a lot better than double if you wanted to represent irrational
numbers in binary form. =)
Two 32-bit ints can represent (the non-integer part of) most (not all)
irrational values to better precision than a double. The algo to find
them is a bit mysterious but very simple. Simple example: 355/113 is
equal to pi with a relative error of less than 1e-7, not bad for two
3-digit numbers. It's not difficult to find two 32-bit ints that would
be better than a double.
