| Data type | Description | Storage |
|---|---|---|
| Double | Double precision floating-point. Will handle most decimals | 8 bytes |
| Currency | Use for currency. Holds up to 15 digits of whole dollars, plus 4 decimal places. Tip: You can choose which country’s currency to use | 8 bytes |
What data type is currency?
Currency variables are stored as 64-bit (8-byte) numbers in an integer format, scaled by 10,000 to give a fixed-point number with 15 digits to the left of the decimal point and 4 digits to the right. This representation provides a range of -922,337,203,685,477.5808 to 922,337,203,685,477.5807.
What are 4 types of data?

How is price stored in a database?
The best type for price column should be DECIMAL. The type DECIMAL stores the value precisely. For Example – DECIMAL(10,2) can be used to store price value. It means the total digit will be 10 and two digits will be after decimal point.

Is double slower than float?
Floats are faster than doubles when you don’t need double’s precision and you are memory-bandwidth bound and your hardware doesn’t carry a penalty on floats. They conserve memory-bandwidth because they occupy half the space per number. There are also platforms that can process more floats than doubles in parallel.
Why is double money bad?
The float and double types are particularly ill-suited for monetary calculations because it is impossible to represent 0.1 (or any other negative power of ten) as a float or double exactly. For example, suppose you have $1.03 and you spend 42c. How much money do you have left? System.
