Does MySQL Have Number Data Type?

MySQL is a popular open-source relational database management system that provides various data types to store different kinds of information. When it comes to numbers, MySQL offers several data types that allow you to store numeric values with different ranges and precision.

Numeric Data Types in MySQL

MySQL provides the following numeric data types:

  • INT

Integer Data Types:

The integer data types in MySQL are used to store whole numbers without decimal places. These data types include:

  • INT: The INT data type can store signed integers with a range of -2147483648 to 2147483647.
  • INTEGER: INTEGER is a synonym for the INT data type, and they can be used interchangeably.

  • TINYINT: TINYINT is used to store small integers with a range of -128 to 127.

Floating-Point Data Types:

The floating-point data types in MySQL are used to store numbers with decimal places. These data types include:

  • FLOAT: The FLOAT data type is used for single-precision floating-point numbers, which can store up to 7 significant digits.
  • DOUBLE: The DOUBLE data type is used for double-precision floating-point numbers, providing higher precision with up to 15 significant digits.

Fixed-Point Data Type:

The DECIMAL data type in MySQL is used for storing exact decimal values. It allows you to specify the precision and scale of the number, making it suitable for financial calculations or any scenario where precision is crucial.


In conclusion, MySQL provides a range of numeric data types to cater to different requirements. Whether you need to store whole numbers or floating-point values, MySQL has you covered. Additionally, by using the DECIMAL data type, you can ensure precise storage of decimal values in your database.

Understanding the available numeric data types in MySQL is essential for designing efficient and accurate database schemas. By choosing the appropriate data type for your numbers, you can ensure optimal performance and accurate representation of your data.
