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?
... John Abbott
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
... John Abbott
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
14:04 Design #1180 (Closed): BigRat(0) unexpectedly compiles! (calls ctor with mpq_t arg): The following code excerpt compiles, but does not do what I expected:... John Abbott
18:01 Design #1124: Move examples directory into doc -- or just change makefile?: Anna now likes the idea.
It may also help solve nicely a silly but annoying problem with the compilation of @CopyI... John Abbott

20:54 Design #1179: Clean up SparsePolyOps-MonomialIdeals: converted code for *@PrimaryDecomposition_MonId@* into a member function.
Anna Maria Bigatti
20:52 Design #1179 (In Progress): Clean up SparsePolyOps-MonomialIdeals: Now that we have made some decisions about the design for ideals of some special sort, clean up *@SparsePolyOps-Monom... Anna Maria Bigatti
20:29 Feature #1178 (In Progress): New function: myPrimaryDecomposition_0dim: Created stucture.
Translated the uppermost function.
Anna Maria Bigatti
20:27 Feature #1178 (Closed): New function: myPrimaryDecomposition_0dim: Translate the code from the CoCoAPackage @PrimaryDecomposition0.cpkg5@ into CoCoALib Anna Maria Bigatti
18:57 Design #1177: File names: use "SparsePolyOps" prefix for pertinent files: Now we have... Anna Maria Bigatti
18:51 Design #1177 (Closed): File names: use "SparsePolyOps" prefix for pertinent files: Use of a prefix is a convenient way to mimick subdirectories. Anna Maria Bigatti

15:11 Feature #1176: interval arithmetic: There is an interval arithmetic sublibrary in the BOOST distribution.
The problem with depending on an external libr... John Abbott
13:41 Feature #1176 (In Progress): interval arithmetic: Implement interval arithmetic (for intervals with rational end points).
Some software libraries already implement ... John Abbott
