Tim,
And, the AP math doesn't seem to like the high bailout used by the dividebrot5 fractal type.
Fixed this, and the change also fixed the bf version of manzpower in Xfractint. The bailout tests were using a long comparison. Changing the comparison to double fixed things (changed bftoint() to bftofloat()). Currently, the Xfractint float version of dividbrot5 is broken, although the bf math version works. Odd. These changes have been committed to the repository. Working with the bn arbitrary math routines leads me to believe that the problem with the bn version of manzpower is not necessarily a lack of precision as indicated in fractalp.c. I have already found a couple of places where a +shiftfactor should not have been used. Jonathan
