Parsley

Parsley provides utilities to convert a string representation of an OCaml numeric value (float, int32, int64, native) to the corresponding value while indicating if a loss of precision occured during the conversion.

How?

Parsley parses the string using arbitrary precision integers and rationals (using the Zarith library) and compares the result it obtains with the one obtained by OCaml's standard of_string utilities (int_of_string, float_of_string ...)

PPX

You can use Parsley's functionnalities on your OCaml source code using the ppx that goes with the library. It generates pretty warning messages using OCaml's warning styles as in the following examples.
