commit 7ddcbce353f5811a8967297eece3fdff7ae04f50
Author: Richard Kreckel <kreckel(a)ginac.de>
Date: Tue Nov 15 00:08:28 2022 +0100
Refactor internal calc_bound() routines.
Reduce them to computation of absolute values of the polynomial's roots
and document that this is known as Landau's inequality. The multiplication
with a power of two is done by the caller.
Also remove the internal fallback computation using the maxcoeff since
this cannot happen. (In the worst case, there is only one non-zero
coefficient 'a'. Then we compute sqrt(a^2) which is not smaller than a.
Otherwise, we compute sqrt(a^2 + x) > a.)
commit d4a58b74cea7c813330aa7813d86713bee205d04
Author: Richard Kreckel <kreckel(a)ginac.de>
Date: Mon Nov 14 23:13:21 2022 +0100
Remove own definition of enable_if<B, T> in favor of...
...the definition provided by <type_traits> since C++11.
commit cdb367739f507337ef1aa5c973e4671c908cf361
Author: Richard Kreckel <kreckel(a)ginac.de>
Date: Mon Nov 14 23:05:47 2022 +0100
[DEBUG] Make some debug output operators compile in factor.cpp...
...for the case when somebody actually #defines DEBUGFACTOR. The operators
must be in the same anonymous namespace in which umodpoly, upoly and upvec
are typedef'ed. (I'm not really sure I understand why but that's what GCC
and CLang are convinced of.)
commit cdce7eb2282dbb095e9ae079da371c78b7c5150e
Author: Richard Kreckel <kreckel(a)ginac.de>
Date: Thu Oct 13 00:12:07 2022 +0200
Optimize some use of CLN's expt_pos() function in factor().
(Not that it's slow or mattered much, but why waste cycles?)
