# uint32

32-bit unsigned integer arrays

## Description

Variables in MATLAB® of data type (class) `uint32` are stored as 4-byte (32-bit) unsigned integers. For example:

```y = uint32(10); whos y```
``` Name Size Bytes Class Attributes y 1x1 4 uint32 ```

For more information on integer types, see Integers.

## Creation

Some array creation functions allow you to specify the data type. For instance, `zeros(100,'uint32')` creates a 100-by-100 matrix of zeros of type `uint32`.

If you have an array of a different type, such as `double` or `single`, then you can convert that array to an array of type `uint32` by using the `uint32` function.

### Syntax

``Y = uint32(X)``

### Description

example

````Y = uint32(X)` converts the values in `X` to type `uint32`. Values outside the range [0,232-1] map to the nearest endpoint.```

### Input Arguments

expand all

Input array, specified as a scalar, vector, matrix, or multidimensional array.

Data Types: `double` | `single` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint64` | `logical` | `char`

## Examples

collapse all

Convert a double-precision variable to a 32-bit unsigned integer.

```x = 100; xtype = class(x)```
```xtype = 'double' ```
`y = uint32(x)`
```y = uint32 100 ```
