Your example showed a 3-digit number being formatted with a requested
precision of 5 digits. The way this was done was by left-padding the
number with 0s until there were 5 digits, but still only 3 digits of
precision. If you truly wanted to format the number with a precision
of 5 digits, it would look like this:
0x123.00
It may happen to do what you want in the printf-style format, but
calling the field "precision" is at best misleading, and there are
other ways to accomplish the same result.

Well, str.format does not use the same syntax as printf.
