. I suspect treachery. Just think about it - the math behind each Mandelbrot pixel. And doing that with a number with hundreds or thousands of decimals. No. There are "shortcut" methods and algorithm hacks to do it , like "interpolating" between 2 images. I am a purist - do it right or it don't count! FractInt has some real tight "C" and "ASM" code - and it took me 3 years on several systems to get past E+100. WTF .
