 > As in MySQL, the `FLOAT` data type stores approximate values. For values such as currency, it is recommended to use the `DECIMAL` type instead.
-> In TiDB, the default precision of the `FLOAT` data type is 8 bits, but in MySQL, the default precision is 6 bits. For example, assuming that you insert `123456789` and `1.23456789` into columns of the `FLOAT` type in both TiDB and MySQL, when you query the corresponding values in MySQL, you get `123457000` and `1.23457`, while in TiDB, you get `123456790` and `1.2345679`.
