There is no way to format numbers in particular way through databind API. However, you can probably make this work with JSON by using `writeRawValue()` method on custom serializer: that allows you to add exact output, without double-quotes. There is actually, I think, also `writeNumber(String)` variant that would similarly allow outputting anything you claim to be number, without validation. These methods are format-specific, meaning that they may or may not work for all format backends; they work fine with JSON.
