Many people are confused about SQL Server's precision and scale. This is unfortunate because choosing the correct values for precision and scale is critically important when you perform math operations using the
22) DECIMAL specifies the data type exact numeric, with the decimal scale specified by the <scale> and the implementation-defined decimal precision equal to or greater than the value of the specified <precision>. 这段描述比较清楚了,小数类型的定义格式为(P,S),即固定精度和小数位数;numeric 要求固...
Represents a numeric value between - 10^38 +1 and 10^38 - 1, with fixed precision and scale.C# Copy public struct SqlDecimal : IComparable, IEquatable<System.Data.SqlTypes.SqlDecimal>, System.Data.SqlTypes.INullable, System.Xml.Serialization.IXmlSerializable...
22) DECIMAL specifies the data type exact numeric, with the decimal scale specified by the <scale> and the implementation-defined decimal precision equal to or greater than the value of the specified <precision>. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 这段描述比较清楚了,小数类型的定...
Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2. In SQL Server, the default maximum precision of numeric and decimal data types is 38. Length for a numeric data type is the number ...

For decimal and numeric data types, SQL Server considers each combination of precision and scale as a different data type. For example, decimal(5,5) and decimal(5,0) are considered different data types.In Transact-SQL statements, a constant with a decimal point is automatically converted into...
The precision and scale of the numeric data types besides decimal are fixed. If an arithmetic operator has two expressions of the same type, the result has the same data type with the precision and scale defined for that type. If an operator has two expressions with different numeric data ty...
This example uses an account_balance column with a DECIMAL data type. It has a precision of 20 and a scale of 2. This means it can store 20 total digits: 18 to the left of the decimal and 2 to the right of the decimal. Example 2: Insert with Decimal ...
The precision and scale determine the maximum limit that you can store in decimal data type. The maximum number of digits to the right of the decimal point (the integer part) is equal to the precision minus scale (p-s). For Example in a Decimal(5,2) column the integer portion can con...
