Binary representation is most natural in digital systems. Binary
ALUs are faster and use less transistor resources than e.g. BCD.
The Zuse, one of the first computers, was binary already.
 
As to Python, it is an interpreted language. Talking about numerics
hardware efficiency aspects in absence of a compiler is ridiculous.
I think the difference between 2/3 and 2.0/3.0 should be easy
enough to grasp, and the standard behaviour should not be changed,
for no good reason at all.

The L numbers are nice, and if we'll get rationals, that would
be very nice, too.
