Tim, I've gotten the floating point version of DivideBrot5 to work in both Fractint and Xfractint. The bf math also works. bn math does not work. Along the way several functions that hadn't been used before in Xfractint were fixed for both the fp and bn math. Also fixed the bn math version of manzpower. Manzpower now works with some small artifacts appearing in the center of lake(s). The artifacts go away when the intlength is increased to 4 (from 2). I'll change the default to 4. The only thing left is to fix DivideBrot5 with the bn math. Jonathan
