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

The following code excerpt compiles, but does not do what I expected:... John Abbott
18:01 Design #1124: Move examples directory into doc
Anna now likes the idea.
It may also help solve nicely a silly but annoying problem with the compilation of @CopyI...

Now we have... Anna Maria Bigatti
18:51 Design #1177 (New): File names: use "SparsePolyOps" prefix for pertinent files
Use of a prefix is a convenient way to mimick subdirectories. Anna Maria Bigatti

13:41 Feature #1176 (New): interval arithmetic
Implement interval arithmetic (for intervals with rational end points).
Some software libraries already implement ...

11:52 Feature #1173: Upper bound for value of poly in an interval
A while ago I read an article about this (perhaps "evaluating a polynomial over an interval"?). I no longer recall m... John Abbott
11:49 Feature #1173 (New): Upper bound for value of poly in an interval
Write a function which accepts a (univariate) polynomial *f* (with rational coeffs), and an interval *[a,b]* with rat... John Abbott

12:20 Slug #1170 (In Progress): SmoothFactor: slow when a factor is found
I have found the slug: I had activated the "clever idea" of testing for @IsProbPrim@ after a factor has been bound, *... John Abbott

23:03 Design #1168: ideal: does const ourGetPtr really need to be private?
It is very convenient having it public :-) :-)
... but today I used it to set the radical/maximal/... flags at the...
