 However, anybody using this library is strongly encouraged to read the [MongoDB Documentation](https://docs.mongodb.org/manual/) as it is often necessary to get close to the raw queries to understand what is happening, especially the [Aggregation Framework](https://docs.mongodb.org/manual/applications/aggregation/).

 Because we're using Spray JSON to do the marshalling, it means that only JSON compatible objects are naturally supported by ScalaD.
 
-However, JSON is missing a few keys object types, such as: `Date`, `UUID` and any distinction between number types.

 MongoDB BSON is also missing a few key object types, such as: `UUID`, `BigInt` and `BigDecimal`. Indeed, MongoDB treats numbers as primitive types and has no support for arbitrary precision numbers.

+If you want to use arbitrary precision numbers, we provide case classes (and Spray JSON marshallers) called `StringBigInt` and `StringBigDecimal` which marshall to `String`. Hopefully Spray JSON will address this magically with a fix to their [issue #44](https://github.com/spray/spray-json/issues/44).
 
 
 Be warned that although Spray JSON will correctly marshall raw `BigInt`s and `BigDecimal`s, MongoDB will silently drop the precision (ScalaD will detect this and create a log for every object that loses precision, so hopefully this is caught at development time).
