16:58 Design #1145 (Feedback): File names, coding conventions: Fns, Ops, Operations? part 2: Confirmed decision: *Ops*. Anna Maria Bigatti

15:02 Feature #1169: New function: RandomLinearForm (CoCoALib): I have added @RandomLinearForm@ to documentation for @SparsePolyRing@.
Probably there should also be a version wit... John Abbott
15:46 Support #847: Doc for BigInt, BigIntOps, BigRat -- should there be BigRatOps?: Good!! go for it! :-)
Anna Maria Bigatti
14:07 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
13:57 Design #1182 (Resolved): "mod" for BigInt: I have improved the documentation about @operator%@ by saying that its sign is the same as that of the quotient, and ... John Abbott

21:51 Design #1182: "mod" for BigInt: A quick look on the internet suggests that @a%b@ is uniquely defined only if @a@ is non-negative and @b@ is positive;... John Abbott

19:29 Design #1182: "mod" for BigInt: hmmm, I had a negative n, I didn't think of the different behaviour with negative entries.
I suppose I need to read ... Anna Maria Bigatti
19:21 Design #1182: "mod" for BigInt: Wait! I need to make a check....
Anna Maria Bigatti
19:12 Design #1182 (Closed): "mod" for BigInt: n % m, with n,m BigInt gives negative values.
Whether this is reasonable when working in FFp, I find it odd for BigI... Anna Maria Bigatti
19:08 Support #847: Doc for BigInt, BigIntOps, BigRat -- should there be BigRatOps?: Should it be @BigIntOps@? Anna Maria Bigatti

12:30 Slug #1181 (In Progress): CpuTime is costly!: It might be useful to have something like @ProgressReporter@ which sets a flag when a time-limit has been exceeded?

12:25 Slug #1181: CpuTime is costly!: I found the problem with an _ad hoc_ program to search for 6x6 matrices with large ratio hadamard/det.
In the main l... John Abbott
12:21 Slug #1181 (Closed): CpuTime is costly!: A call to *@CpuTime()@* is quite costly (on my machine with Fedora 25 Linux).
This means that a calls to @CheckFo... John Abbott
11:18 Design #1124: Move examples directory into doc -- or just change makefile?: I have added a dirty hack to @doc/Makefile@ so that @CopyInfo@ can be compiled even when @libcocoa.a@ does not exist

11:05 Design #1180 (Resolved): BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): The impl has been modified:
* @BigInt@ ctor from @mpz_t@ and from @std::string@ now take 2 args, and are @private@; ... John Abbott

17:58 Design #1180: BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): Since the ambiguity of @BigInt(0)@ derives from the fact that @std::string@ has an implicit ctor from @char*@, it may... John Abbott
11:59 Design #1180: BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): I have replaced the ctor @BigInt(mpz_t)@ by one which requires a second arg (@CopyFromMPZ@), and then changed all cod... John Abbott

20:24 Design #1180: BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): The situation is more complicated than I'd like. Here I'll write about @BigInt@, but it applies just as much to @Big... John Abbott
14:34 Design #1180 (In Progress): BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): JAA thinks there is little hope that the language rules for C++ will change (in the forseeable future) to forbid an "... John Abbott
14:10 Design #1180: BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): The problem turned out to be that *@2/3@* is evaluated by the compiler to produce @0@ (integer division); this is the... John Abbott
