Unless I am mistaken, FractInt does arbitrary precision math only for Mandelbrot and Julia built in formula types. You can't select arbitrary precision math for formula types.
Page 166 of Fractint.doc for 20.4: Wes Loewer wrote an arbitrary precision library in both 80x86 assembler and C, and the Stone Soup team incorporated Wes's library into Fractint. Initially, support was added for fractal types mandel, julia, manzpower, and julzpower. . . . So how far can you zoom? How does 10^1600 sound--roughly 1600 decimal digits of precision. . . . Note: many of Fractint's options do not work with arbitrary precision. To experiment with arbitrary precision at the speedier ordinary magnifications, start Fractint with the debug=3200 command-line option. With the exception of mandel and manzpower perturbations, values that would normally be entered in the Parameters and Coordinates screens need to be entered using the command-line interface or .par files. Other known things that do not yet work with arbitrary precision are: biomorph, decomp, distance estimator, inversion, Julia-Mandel switch, history, orbit-in-window, and the browse feature. - Hal Lane ######################## # hallane@earthlink.net ########################

Hmmm, so if you started Fractint with debug=3200 and a formula par, it would calculate the formula using arbitrary precision? -- David gnome@hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com http://clanjones.org/david/ http://dancing-treefrog.deviantart.com/
