[Python-ideas] Re: division of integers should result in fractions not floats

when dividing two integers, the result is a float, which means we immediately lose precision. This is not good if you want to use code which supports higher precision. Decimals come to mind, but also sympy. This loss of precision could be avoided if the result of a division is a fraction instead: a fraction is exact.

Please read http://python-history.blogspot.com/2009/03/problem-with-integer-division.htm... . In short, it was a feature of Python's predecessor, ABC. But it turned out to be not as good as it seemed at first glance. Fixing this mistake was one of causes of creating Python.
