Split John Abbott

16:35 CoCoALib Support #847 (Feedback): Doc for BigInt, BigIntOps, BigRat -- should there be BigRatOps?

I have split @BigRat@ into @BigRat@ (class defn, ctors, and accessors) and @BigRatOps@.
All files have been updated;... John Abbott

Prototype John Abbott

17:58 CoCoALib Slug #1181: CpuTime is costly!

I now have a prototype which works well in one small test.
The new design does not mimic the old interface... :-/

16:36 CoCoA-5 Feature #1122: New fn: RandomLinearForm

I have reversed the loop in @RandomLinearForm@ (in @SparsePolyRing.C@). Now it is significantly faster.
But why w... John Abbott

I have added @RandomLinearForm@ to documentation for @SparsePolyRing@.
Probably there should also be a version wit... John Abbott

Discussion John Abbott

14:07 CoCoALib Support #847 (In Progress): Doc for BigInt, BigIntOps, BigRat -- should there be BigRatOps?

I like the name @BigIntOps@. The file does also contain several fns which accept @MachineInt@ args (and several whic... John Abbott
