Uh, I don't know what you are complaining about the GAP to Mathematica could widen? I work heavily on exactly that goal!!! - increasing the distance to their Gröbner bases implementations ;-). I would make myself ridiculous, if I would do benchmarks against it. Just for conformity, I enter the

I see. Yes I agree it should be false. Consider: CIF(RIF(0)) != CIF(RIF(-1, 1)) True RIF(0, 0) != RIF(-1, 1) False That these two comparisons should be different makes no sense, does it? Also why is it that CIF(0) seems to not have an interval, while CIF(1) does? On Jul 13, 4:35 pm, Nick Al

Hi Nils, Your message sent to my old email address in Nottingham, or I would have replied sooner ;) I'm forwarding the reply to sage-devel. No, it is not my code. The only problem is that the function calls E.lseries().L_ratio(), and L_ratio() calls misc.verbose() without importing the misc mo

Some weird behavior in ComplexIntervalField: CIF(0) != CIF(-1, 1); This should be false (as the value 0 is contained in both intervals), but it returns true (using whatever version is on sagenb.org). A little deeper: print CIF(0); 0 print CIF(1); [1. .. 1.0

Hi all, Recently David Kirkby tried to compile sage on solaris express and it blew up on pari. Turns out the pari shared library is build without any PIC flag and that caused his linker to just give up. Turns out that the problem is in fact widespread across a number of archs where the linker e
