change the format string of the double to string function jsut before the last while loop to
%.3f
to make it so the display works right.
Also my possibility generator only handles [] sections of the form [x-y] not [abcd], that shouldn't be a hard change if that pattern turns up. Mine will also break if there's a very large amount of posibilities (all numbers greater than 1 would run out of ram for instance). I can make it handle nested structures (a [] inside a () or something like that) if they turn up (I doubt they will though).
