Use a period to separate partial monetary units, like cents, from whole monetary units. For example, 2.15 specifies 2 dollars and 15 cents.

You don't need to enclose currency or monetary data in single quotation marks ('). While you can specify monetary values preceded by a currency symbol, SQL Server doesn't store any currency information associated with the symbol, it only stores the numeric value.

Warning

You can experience rounding errors through truncation, when storing monetary values as money and smallmoney. Avoid using this data type if your money or currency values are used in calculations. Instead, use the decimal data type with at least four decimal places.

Convert money data

When you convert to money from integer data types, units are assumed to be in monetary units. For example, the integer value of 4 is converted to the money equivalent of 4 monetary units.

The following example converts smallmoney and money values to varchar and decimal data types, respectively.

DECLARE @mymoney_sm SMALLMONEY = 3148.29,
    @mymoney MONEY = 3148.29;

SELECT CAST(@mymoney_sm AS VARCHAR(20)) AS 'SM_MONEY VARCHAR(20)',
    CAST(@mymoney AS DECIMAL) AS 'MONEY DECIMAL';

Here is the result set. Because the decimal type in the example doesn't have a scale, the value is truncated.

SM_MONEY VARCHAR(20)           MONEY DECIMAL
------------------------------ ----------------------
3148.29                        3148
