Hi all,

I'm writing a JSON parser in pure OCaml and have encountered an issue with small float values:

10 zeros in between

I haven't found precise limit, but as a rule of thumb (not precise), for a positive float value to keep its precision, it should not be smaller than 1.00000000001e-312. To use JSON as precise serializer, it would be necessary to preserve accuracy.

I checked https://github.com/ocaml/Zarith and it supports only big int & quotients, not floating point.

For values smaller than the limit above, should I just treat as 2 values: (normalized: float, exponent: float), so we will have:

Comments and suggestions are appreciated. Thanks.
