The print statement/function does no magic at all in specifying how
numbers look like when. The apparently magical formatting is done by the
%-operator and for {}-style formatting, the obj.__format__().
If you're using the {}-format, you can override .__format__() to define
your own formatting mini-language.
If you need to, you can monkey patch format() so that it wraps int/float
in Engineer wrapper that defines Engineer.__format__() to whatever
formatting style you're using.
