# int8

Converts to 8-bit signed integer.

## Syntax

* Y = int8(X)

## Input argument

* X - a matrix of double, single or integers.

## Output argument

* Y - a matrix of 8-bit integer.

## Description

int8 converts value to 8-bit integer type.

The value is rounded to the nearest int8 value on conversion. A value that is above or below the range for an int8 class is mapped to one of the endpoints of the range \[-128, 127].

## Example

```matlab
A = [1 -255 -120 127 128 215]
B = int8(A)
```
