+#stores a rational number to perfect precision as a ratio of longs
+#combines with ints to produce a frac ( except __rpow__() ) and with floats to produce a float
+#comparisons with floats might not work perfectly for very similar numbers, I need to test out the float casting a bit
+#it's possible that order w/r/t floats that differ near the limit of precision may not work properly, and even break ordering
+#one solution would be casting floats to fracs instead of vice-versa
