I'm quite sure something like this (doing multiple squarings without IFFT in-between, just subtracting 2 in the frequency domain) was mentioned in the FAQ at some point, but I can't find it anymore -- anyhow, your problem is that you lose too much accuracy. For your scheme to work well you'd have to pick a much larger FFT size, which would defeat any speedup you'd gain. :-) /* Steinar */ -- Homepage: http://www.sesse.net/ _______________________________________________ Prime mailing list [EMAIL PROTECTED] http://hogranch.com/mailman/listinfo/prime
