Hi Jim, Sorry it took so long to get back to you on this. The problem with decimal.o rears its head again: make[1]: *** No rule to make target `decimal.o',...
Yes, decimal.o has been removed. It has not been used since original primeform days. I simply removed it, but must have fergot to rip it out of the pfglue's...

ABC2 (137*2^$a-1)/3 a: from 27151 to 28101 step 2 The ABC2 file above gave a 476/476 failure rate, running PFGW Version 20041129.Win_Stable (v1.2 RC1d) [FFT...
... PFGW's suboptimal for such types anyway, so I wouldn't use it for them if I were you: phil@nonospaz:GCN$ time ./glprov.athlon -q '(137*2^28101-1)/3' ...
There is more than one way to skin a cat with PFGW (sometimes). Yes, the expressions (x*2^n-1)/3 are not optimal in PFGW. However, with the script file: ...
... Ah, I see, thanks, Jim. More generally, for N = (k*2^n +/- 1)/D use SCRIPT to compute Mod(b,N)^(N-1) = Mod(Mod(b,D*N)^(N-1),N) and then POWMOD gets to use...
... Even more general: N = (some_optimized_form)/D then SCRIPT Mod(b,N)^(N-1) = Mod(Mod(b,D*N)^(N-1),N) Keep in mind, that the "some_optimized_form" can be a...

Yes, MAXF was "mis" spelled MAFX and MINF was MINX, so neither worked. I have been looking for a good place to send a new (win32 only) build. I guess now is a...
A new version has been uploaded. WARNING!!!!! This version is highly experemental. I would NOT recommend using this for proving numbers, without using an...
I've been using the 20041216 alpha version for about three weeks and have been able to write script files using the POWMOD function to make use of the new...
Several things, 1. The problem with the LEN(x[,y]) function, is that the mpz_sizeinbase() function in GMP will give the correct result, or one larger than the...
... It appears mpz_sizeinbase() only looks at the number of bits. An exact result in base b can be found like this: First find the leading bits (e.g. 32 bits)...
I think your alternate solution is much better than we have now. It would not cause much overhead memory wise, as all we are doing is putting anouther Integer...

The problem has been (almost) fixed. the len function is 100% accurate, and quick with no additional memory allocation for base 2,4,8,16,32. For length of a...
... The last line makes no sense. "-1" disappeared in the expression. len(10^6000000) is 6000001. "trivially factors as" shouldn't be there with -f0, and...
I have a small request (or at least I think it is small). Could WinPFGW put the current line, PRP count/prime count, and PRP status into the tool tip text on...
Good simple request. The format (while running, and not in "stealth" mode), will look like: "WinPFGW - line %d, %0.2f%% of %s (%d prps)" or "WinPFGW - line...
