Apparently just for the fun of it, the 'mult' option colors the pixels by multiplying the iteration count of escaping points by their real divided by maginary values at the time they escape. (...) In the C languaje is the possibility of branching on the results of an assignment. That is, you can write (z=c) and perform a certain function if the assignment happened to clear zed, that is to make it zero.
The sheer variety of coloring options makes me want to sujest a way to put the enumerated functions (atan, atanh, etc.) into the z-screen, where there are already a lot of options for determining when an escape will occur. Perhaps, also, there could be a function applied to zed after an escape and before the color number is determined, allowing you to put the absolute value of zed into the real part of zed before FracTint determines the colour. In other words, the user might opt to apply the natural logarithm to zed before fractint's own logmap feature is applied to the number for the colour. _______ In Mathematics, there is never a bigger half.
