BigInt wrapper used with decimals

[nicholaschiang]

When the useNativeBigInt option is enabled, this package attempts to wrap decimals (e.g. 0.990011990070343) in the native BigInt wrapper which fails (as they're obviously not integers). Instead, json-bigint should be smart enough to realize that a long floating point number is not an integer and thus should not be wrapped at all.

Here's the error I'm encountering:

[sidorares]

can you provide simple repro example?

[nicholaschiang]

@sidorares I suspect this is actually already fixed in master:

          // Number with fractional part should be treated as number(double) including big integers in scientific notation, i.e 1.79e+308
          return _options.storeAsString
            ? string
            : /[\.eE]/.test(string)
            ? number
            : _options.useNativeBigInt
            ? BigInt(string)
            : new BigNumber(string);

It just hasn't been released to NPM yet (see #74) and thus I'm seeing this bug in production.
