# Module Decimal

    module Decimal: sig .. end

The `decimal` type alias provides more readable serializations to s-expressions, at the cost of lower precision. For example:

        # sexp_of_decimal 3.000000000001;;
        - : Sexp.t = 3
        # sexp_of_float 3.000000000001;;
        - : Sexp.t = 3.0000000000010000889

Also, the decimal sexp-converter will fail when provided with `nan` or `infinity`.

        # float_of_sexp (Sexp.Atom "nan");;
        - : float = nan
        # decimal_of_sexp (Sexp.Atom "nan");;
        Exception:
        (Sexplib.Conv.Of_sexp_error (Failure common.ml.Decimal_nan_or_inf) nan).

    type t = float
