I am working on an application that converts to or from as many bases as possible. It will also do arithmatic in those bases. Some of the ones I have already done are: -64 to 64, phinary, (-1±i), sqrt(x), Quater-Imaginary, Improper fractional bases, (-1+i sqrt(2) / 2) and also one similar to the last but involving the number 7.. that's a cool one too, can't remember off the top of my head though. Anywho, I was wondering if anyone would be interested in a 'one-size-fits-all' convertor/calculator? I'm making it with Qt so it won't be magic and fairies, just some freeware I made in my freetime :) Also: Any other base suggestions are welcome with open arms!
