What is the difference between bigdecimal and decimal in MySQL?

In MySQL, decimal and BigDecimal are both data types used to store precise numerical values. The main difference between them lies in their storage space and range.

1. Storage space:
2. Decimals use a fixed amount of storage space, based on the specified precision and number of decimal places, and can store up to 65 digits for the integer part and 30 digits for the decimal part.
3. BigDecimal can dynamically adjust the storage space based on precision and number of decimal places, allowing it to store larger numbers.
4. Range:
5. The supported range of decimal numbers is from -10^65 to 10^65.
6. Bigdecimal can store a wider range of numerical values due to its variable storage space, but the actual range depends on the storage space being used.

In summary, BigDecimals can store a larger range of numbers compared to Decimals, but this also means they require more storage space. Therefore, the choice of which data type to use should be based on the specific needs of the situation.
