where possible, use python fractions for Rational #11081
Comments
fractions module suffers from the same issue fixed in #11019 |
caching of igcd was not working properly. Fixed this in #11089 |
Maybe we should merge with the polys, which uses gmpy types when they are available (which are even faster). |
I've tried using gmpy mpzs here https://github.com/isuruf/sympy/tree/gmpy. Didn't have time to check whether there are speed improvements though. Using gmpy mpqs will take some more work though, because Rational class keeps the two separate ints. |

Since we have dropped support for 2.5 we can use the fractions module for Rational internals. The
gcd
method could also replaceigcd
