money and smallmoney

Monetary values entered with the E notation are interpreted as float. This may cause an entry to be rejected or to lose some of its precision when it is stored as a money or smallmoney value.

money and smallmoney values can be entered with or without a preceding currency symbol such as the dollar sign ($), yen sign (¥), or pound sterling sign (£). To enter a negative value, place the minus sign after the currency symbol. Do not include commas in your entry.

You cannot enter money or smallmoney values with commas, although the default print format for money or smallmoney data places a comma after every three digits. When money or smallmoney values appear, they are rounded up to the nearest cent. All the arithmetic operations except modulo are available with money.
