# Constants
> 32-bit signed integer mathematical constants.
## Usage
```javascript
var constants = require( '@stdlib/constants/int32' );
```
#### constants
32-bit signed integer mathematical constants.
```javascript
var c = constants;
// returns {...}
```
- [`MAX`][@stdlib/constants/int32/max]: maximum signed 32-bit integer.
- [`MIN`][@stdlib/constants/int32/min]: minimum signed 32-bit integer.
- [`NUM_BYTES`][@stdlib/constants/int32/num-bytes]: size (in bytes) of a 32-bit signed integer.
## Examples
```javascript
var objectKeys = require( '@stdlib/utils/keys' );
var constants = require( '@stdlib/constants/int32' );
console.log( objectKeys( constants ) );
