It seems you have no choice but to keep the string representation around,
then. There are other possible anomalies with numbers, like "leading zeros",
where a conversion to number and back would transform 0042 -> 42. Likewise
with 1e2 -> 100 and so on. When transformed into numbers, you lose that
information.

Note that 0.2 is an infinite binary fraction, i.e. if you go binary and
back under most JSON implementations, you'd always get a result depending
on the underlying precision, rounding strategies, etc.
