In MSSQL, the MONEY and SMALLMONEY types are specialized variants of DECIMAL with fixed decimal precision:
MONEY is equivalent to DECIMAL(19,4) (19 total digits with 4 decimal places)
SMALLMONEY corresponds to DECIMAL(10,4) (10 total digits with 4 decimal places)
When mapping these to Rust, the most suitable data types are rust_decimal or bigdecimal to preserve exact precision without floating-point errors.
In financial software development, the MONEY data type is widely used. Therefore, we strongly recommend adding support for the MONEY type in sqlx-oldapi.
This PR extracts shared codes into decimal_tools.rs included with testing code.
