Normalize our number encoding (#3370)

Browse Source 
Our Number encoding consists of two parts. Firsts we convert the float
into f * 2**exp, then we uvarint encode f and exp. However, we didn't
normalize f so in theory we could end up with multiple representations
of the same number.

This changes the representation to make the f the smallest possible
integer that fulfills the formula above.

For example we used to encode 256 as (0x100, 0) but with this we instead
encode it as (0x01, 8).

Fixes #2307
