As a SQL developer myself, I always try to use SQL Decimal data type as decimal (9, 2) which consumes the least storage, 5 bytes on disk and offers better performance. Among the available Field Sizes is Decimal: Decimal fields have decimal precision of 28, and store numbers from –10^28–1 through 10^28–1 (or –10^38–1 through 10^38–1 in ADPs). It becomes very essential for SQL developers to choose the correct data types in the table structure while designing and modeling SQL databases. The so-called round up means that the decimal part to be rounded is regardless of its size, […] In SQL Server Database, each column of a table, all the local variables, and parameters must have a data type. In SQL server, the data of floating-point value is stored by round up. Floating point data types are used to store decimal numbers. However, DECIMAL required a lot of storage space ( 17 bytes ). For instance, decimal (4,2) indicates that the number will have 2 digits before the decimal point and 2 digits after the decimal point, something like this has to be the number value- ##.##. In earlier versions of SQL Server, the default maximum is 28. NUMERIC determines the exact precision and scale.
