# Function randomInt

Return a random integer number larger or equal to `min` and smaller than `max`
using a uniform distribution.


## Syntax

```js
math.randomInt()                // generate a random integer between 0 and 1
math.randomInt(max)             // generate a random integer between 0 and max
math.randomInt(min, max)        // generate a random integer between min and max
math.randomInt(size)            // generate a matrix with random integer between 0 and 1
math.randomInt(size, max)       // generate a matrix with random integer between 0 and max
math.randomInt(size, min, max)  // generate a matrix with random integer between min and max
```

### Parameters

Parameter | Type | Description
--------- | ---- | -----------
`size` | Array &#124; Matrix | If provided, an array or matrix with given size and filled with random values is returned
`min` | number | Minimum boundary for the random value, included
`max` | number | Maximum boundary for the random value, excluded

### Returns

Type | Description
---- | -----------
number &#124; Array &#124; Matrix | A random integer value


## Examples

```js
math.randomInt(100)    // returns a random integer between 0 and 100
math.randomInt(30, 40) // returns a random integer between 30 and 40
math.randomInt([2, 3]) // returns a 2x3 matrix with random integers between 0 and 1
```
