What are the characteristics of the numeric data type in SQL?

In SQL, the numeric data type is used for storing precise numbers, typically used for storing decimal or integer values. Characteristics of the numeric data type include:

1. High precision: The numeric type can store very accurate numbers, often supporting the storage of hundreds of decimal places.
2. High precision calculation: The exactness of the numeric type allows for avoiding rounding errors during the calculation process.
3. Fixed length: The length of a numeric type is fixed, meaning that it will occupy the same amount of storage space even if the stored value does not require all of the digits.
4. Large storage space: Because of the precision and fixed length of numeric types, they require more storage space than other data types.

In general, the numeric data type is suitable for scenarios that require high precision and accurate calculations, but it is also important to consider its characteristic of taking up a large amount of storage space.
