Happy new year folks! Thanks for all the work on PFGW, seems to be running smooth with -a1. Here was a bit of miscommunication (p on my list is the n-th...
Pari is miscalulating Phi(n,x) for negative x's. For example, it reports Phi(255,-10708^6)/3061 is composite. PFGW output: PFGW Version 20020311.x86_Dev...

I don't think these problems are simply due to needing (-n)^e Here look: c:\prime\openpfgw\openpfgw>pfgw -q"-1*(-10^3+1)" PFGW Version 20021224.Win_Dev (Beta...
You are right Phil. It is op precidence (or parser design). The "flaw" also apears to be in bc: bc 1.03 (Nov 2, 1994) Copyright (C) 1991, 1992, 1993, 1994...

I have found this "fix". I will toss it out and see who bites at it: I have tried to remove the unary minus. Now a unary minus of -c is treated as 0-c What...

I've got a number that PRP declared probably prime which then failed testing by both Proth and PFGW. Since this was the first time I've seen that happen and...
... It's worth running pfgw with the '-a1' switch to force it to use extra safe FFTs. '-a2' for even more safety. The composites tell you their lowest 64-bits...
