20:41 Feature #1210 (Closed): New Fn: make public "coefficients" (of poly wrt a given PP basis)

I have opted for the KISS solution -- we can make fancier versions in the future is there is need for them!
I have c... John Abbott

20:16 Slug #1680 (Closed): FloorLog2 or SizeInBase?

After discussion with Anna we have decided that @SizeInBase@ is obsolete; so the original question here is no longer ... John Abbott

20:08 Feature #1684 (Closed): RandomNBitPrime - new fn

This was completed about 2 months ago. There is even doc!
Not sure how one could test it: perhaps range check and I... John Abbott

20:04 Feature #1488: BuiltIn Interreduce-Function

Anna! Please document and close this issue!

19:56 Feature #718: Insert calls to CheckForInterrupt

Nico Mexis asked whether there could be a check for interrupts inside the factorizer.
This will much easier to achie... John Abbott

19:48 Design #1693 (Resolved): SizeInBase: obsolete

Anna agreed.
I have moved the code to @obsolete.H@ and @obsolete.C@ (from BigIntOps@).
All tests pass.

I think *@SizeInBase@* is not really useful (cannot think of any situation).
Also it can easily be implemented by ca... John Abbott

I implemented a prototype @PrimeSeq1ModN@ class for a student, and he needed something like a @JumpTo@ function.
So ... John Abbott

17:39 Feature #1692 (In Progress): Suggestion: Add "JumpTo" function to prime iterators

Consider adding a *@JumpTo@* mem fn to iterators (for prime numbers)... John Abbott

17:27 Design #1678 (In Progress): Unsigned long for indexes (& sizes?)

The students in my course, who already had some experience in C++ and other similar languages,
definitely expected @... John Abbott

12:22 Design #1691: Random and threadsafe?

Alternative: create a version "threadsae: which uses a mutex/lock... might be slow, but should be safe.

12:13 Design #1691 (New): Random and threadsafe?

Random fns should also accept a random source so they can be used in a multi-threaded program.
