Just curious, what is your use-case in which you need better support for fractions?

- callesgg 13y agoA simple example: (i will use decimal instead of binary as it is easier and binary suffers from the same stuff but for other numbers) (10/3)x(9/4) == 7.5 but due to the fact that computers store the value instead of the fraction it would come out as something like 7.4999999999 cause instead of doing (10x9)/(3x4) it would do 3.3333333333333 x 2.25
- giovannibajo1 13y agoThis looks like a case for decimal floating point, not fractionals. In Python: >>> from decimal import Decimal as D >>> D("10")/D("3") * D("9")/D("4") Decimal('7.50000000000000000000000000')
