It was special cased too soon :-)

def intToStr(num, radix=10):
   if num < 0: return '-' + intToStr(-num, radix)
   if num < radix: return "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"[num]
   return intToStr(num // radix,radix) + intToStr(num % radix,radix)

Works a lot better with bin as defined above!
