Description
The TJsonDecimal128 type offers support for handling Decimal128 data in JSON.
RAD Studio supports the use of TJsonDecimal128 through the MongoDB database driver, FireDAC.
FireDAC provides a built-in mechanism that works with Decimal128 data types from MongoDB.
Use the Decimal128 data types via FireDAC's MongoDB support.
