When unloading data, which file format preserves the data values for floating-point number columns?

Show Suggested Answer Hide Answer
Suggested Answer: D

When unloading data, the Parquet file format is known for its efficiency in preserving the data values for floating-point number columns. Parquet is a columnar storage file format that offers high compression ratios and efficient data encoding schemes. It is especially effective for floating-point data, as it maintains high precision and supports efficient querying and analysis.
