Ticket #1075 (closed defect: invalid)
[with patch] sync'ing hashes for fraction fields and rings
|Reported by:||jbmohler||Owned by:||somebody|
The attached patch provides a custom hash function for fraction field elements so that fractions with a denominator of 1 hash the same as the hash of the numerator as an element in the ring. A charming side effect is that hash is *much* faster now for fraction field elements of MPoly's over QQ.
This fixes some bugs (IMO) in the subs method of ParentWithGens? when passing a dictionary.
I don't think there is any problems with hash's changing from one version to the next -- I guess there might be something I'm missing here.
