Read the string as RingElem in QQ, then call AsINT/RAT for RingElem.
This is slower then the a... - 09:33 CoCoA-5 Feature #1821 (Feedback): AsINT, AsRAT could also take a STRING
- I would find it handy to have AsINT, AsRAT.
There is a trivial implementation I can do. - 08:32 CoCoA-5 Bug #1820 (New): Manual: why doesn't "?Commands and Functions for STRING" show the function RingElem?
