![]() ![]() Whereas, the s or scale indicates the maximum number of digits that can be stored to the right of the decimal point. The precision must be a value from 1 to 38. When declaring a or decimal or numeric column, the precision and scale can be specified, like decimal( p, s) or numeric( p, s), where the p or precision indicates the maximum total number of digits that can be stored, both to the left and to the right of the decimal point. ![]() The numeric datatype is functionally equivalent to decimal.Īllows you to store monetary or currency values accurately in the range from -214,748.3648 to 214,748.3647.Īllows you to store monetary or currency values accurately in the range from -922,337,203,685,477.5808 to 922,337,203,685,477.5807. Valid values are from 10 ^38 +1 through 10 ^38 - 1. Stores fixed precision and scale numbers. Stores integer values in the range from -32,768 to 32,767. Stores integer values in the range from 0 to 255. Numeric data types are normally used to store data like price, salary etc.Īllows you to store a value 1, 0, or NULL. Here, max indicates that the maximum storage size is 2 GB. The following shows how to create a table with decimal columns.Stores fixed-length character string. ![]() For Example Decimal(3,2), Decimal(5,2) & Decimal(9,2) will all use 5 bytes of disk space, although the Decimal(9,2) can store more numbers. The precision from 1 to 9 will require 5 bytes of disk space. The precision determines the storage size, that a decimal number takes in the disk. If you want to store number larger than that, you need to use the float data type Size in Bytes Hence in decimal(5,2), you can store from number -999.00 to 999.99. For Example in a Decimal(5,2) column the integer portion can contain only 3 digits (5-2). The maximum number of digits to the right of the decimal point (the integer part) is equal to the precision minus scale (p-s). The precision and scale determine the maximum limit that you can store in decimal data type. For Example, 123 will become 123.00 Maximum Limit If the number does not have a decimal position (like an integer number), then SQL Server will add implicitly. For Example, 123.456 is rounds to 123.46 in a decimal(5,2) column. If you try to insert a number, which has more decimal position than the column permits, SQL Server will round it off. For Example, the decimal(5,2) column will store the number in 2 decimal places. The scale defines the number of decimal digits that you can store. ![]() The SQL Server allows a minimum precision is 1 and maximum precision of 38. The number includes both integer & fractional parts.įor Example 123.45 has a precision of 5 as there is a 5 digits in that number. The Precision defines the maximum number of digits that you can store. One is (p) Precision & the other one is (s) scale p (precision) ![]()
