In ptic it is not easy to find the descrip... - 09:17 CoCoA-5 Feature #857: floor, ceil, and NearestInt for RingElem in CoCoA-5?

Perhaps...

- 16:07 CoCoA-5 Feature #1243: New function: Read a string into a list (of RingElem) -- CoCoA-5
- At the moment, input is only via *@GetLine@*, which naturally reads a whole line as a string.
Currently we cannot ... - 14:28 CoCoA-5 Feature #1243: New function: Read a string into a list (of RingElem) -- CoCoA-5
