# MySQL Numeric Data types

# Overview

In this tutorial, we will learn MySQL Numeric Data types. MySQL supports many data types to store numeric data, such as integer, floating-point, and fixed-point types.

## Integer Data Types

The integer data type is used for storing whole numbers.

Whole numbers do not have decimal digits.Â For example, 25 is a whole number and 32.7 is not a whole number.

The following is the list of numeric data types:

Integer Data type |
Description |

TINYINT |
Used for very small integer |

SMALLINT |
Used for small integer |

MEDIUMINT |
Used for medium-sized integer |

INTEGER |
Used for normal integer |

BIGINT |
Used for large integer |

**Floating-Point Data Types**

The floating-point data types are used to represent approximate-value numbers that have an integer part, a fractional part, or both. The floating-point data types are:

*FLOAT* – Single-precision floating-point number

*DOUBLE* – Double-precision) floating-point number

These types represent values in the native binary floating-point format (IEEE 754).

## Syntax

The *FLOAT* data type is assigned using the syntax:

*FLOAT (N, D)*

N is the maximum number of decimal digits and D is the number of digits following the decimal point. A single-precision floating-point integer is accurate to approximately 7 decimal places.

The *DOUBLE* data type is assigned using the syntax:

*DOUBLE (N, D)*

N is the maximum number of decimal digits and D is the number of digits following the decimal point. A double-precision floating-point integer is accurate to approximately 15 decimal places.

**Fixed-Point Data Types**

The fixed-point data type in MySQL is *DECIMAL*. *DECIMAL* data type is used to represent exact-value numbers that have an integer part, a fractional part, or both.

All values of the* DECIMAL* column have the same number of decimal places and are stored exactly as specified.

The *DECIMAL* data type is assigned using the syntax:

*DECIMAL (N, D)*

N is the maximum number of significant digits that can be stored and D is the number of digits following the decimal point (from 1 to 255).
