> When using the "Infer Schema" strategy on JSON Record Readers (JsonPathReader, JsonTreeReader, e.g.), all fractional numbers are inferred as floats, meaning there can be some truncation if the value can only truly fit in a double. The inference code is meant to fit the field to the widest of its type, so it should infer fractional fields as doubles rather than floats.
