### Description Druid supports Double data type which is an Approximate Numeric Types. Is it on the roadmap anywhere to add support for Exact Numeric Types? Highest numerical precision we can get with druid is the double (64bit) data type. Due to the nature of binary storage format, we would have 53 meaningful bits, which means 15 meaningful decimal digits for sure. ( 53 log10(2) ≈ 15.955 ). As an example of Exact Numeric type: BigQuery has support for NUMERIC data type which gives 38 digits of precision and 9 decimal digits of scale. This is the ideal field for financial reporting, or any high precision calculations. ### Motivation Support for data with High precision ranging that contains very small and very big data points without data loss. - Financial reporting is a big motivating use-case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
