The display of numbers in the decimal system with a sign is such a
ridiculous notion...

Please remember what a positional system is; if B is the base, then
abcde means

   e + d*B + c*B**2 + b*B**3 + a*b**4

and -abcd means

   -e - d*B - c*B**2 - b*B**3 - a*b**4

I don't find this ridiculous, whether B is 10 or 16.

This is by design; read PEP 237.

In phase B.1, it will be right.
