Tim:
On the fifth hand, I doubt anyone would want to add new % format codes for bases {2..36} - {2, 8, 10, 16}.
So, just add one general one: %m.nb with n being the base. If n defaults to 2, you can read the "b" as either "base" or "binary". Literals: 0b(5)21403 general 0b11001101 binary Conversion functions: base(x, n) general bin(x) equivalent to base(x, 2) (for symmetry with existing hex, oct) Type slots: __base__(x, n) Backwards compatibility measures: hex(x) --> base(x, 16) oct(x) --> base(x, 8) bin(x) --> base(x, 2) base(x, n) checks __hex__ and __oct__ slots for special cases of n=16 and n=8, falls back on __base__ There, that takes care of integers. Anyone want to do the equivalent for floats ?-) Greg Ewing, Computer Science Dept, +--------------------------------------+ University of Canterbury, | A citizen of NewZealandCorp, a | Christchurch, New Zealand | wholly-owned subsidiary of USA Inc. | greg@cosc.canterbury.ac.nz +--------------------------------------+
