[JAA see file @ShortTerm/oscar.C@] - 10:57 Design #377 (In Progress): IsDivisible -- exact semantics?
- The problem with dividing @4/2@ in @ZZ/6@ is that the true answer is @2@ in @ZZ/3@ -- a different ring! The answer ...

- While dealing with issue #248 I realised that the exact semantics of @IsDivisible@ are not clear.
The problem is whe...

- 17:31 Feature #300 (Closed): Add fault tolerant rational reconstruction to library
- The code was effectively tested while updating the article. So I'm regarding it as OK. Closing!
