- Add doc for *@NBM@* and *@SOI@*.
Also add examples and tests.

Code probably still needs to be cleaned.
Documentation (file @ApproxPts2.txt@) is complet... -

Implemented, documented; appears to work fine.
So closing now. -

17:13 Feature #313 (In Progress): Elim(vector<long>) as PPOrderingCtor
- Same as lex, StdDegLex, ... also *Elim(vector<long>)* should be implemented as a *PPOrderingCtor*

It may not be relevant, but I... -

Now we have *Ge...

-
- Should we call it *ZeroValue* instead of *NotNonZero*?
And *NegativeValue* instead of *NotNonNegative*? -
- All CoCoALib errors which refer to zero are:
*@BadPwrZero, DivByZero, LogZero, MemPoolZero, NotNonZero, ZeroModulus, ... -
- The error *@ZeroRingElem@* is used for:
@StdDeg, LC, Monic, IsIrred, MaxExponent, wdeg (& CmpWDeg & CmpWDegPartial),... -
- I've found the error *ERR::NotNonZero*. Should we remove *ERR::ZeroRingElem*?
(and LogZero, ZeroModulus,..)
-
- While writing this I gave myself the answer "probably NO", this is the reason:
* *general case*: just one constructo... -
-
- That's more worrying that two compilers complain.
Despite comments in the file @Main.C@, as far as I can tell @FreeM...
