# int2slice

## Usage

```javascript
var int2slice = require( '@stdlib/slice/base/int2slice' );
```

<a name="main"></a>

#### int2slice( value, max, strict )

Converts an integer to a [`Slice`][@stdlib/slice/ctor] object, where `max` specifies the index upper bound.

<!-- eslint-disable stdlib/no-redeclare -->

```javascript
var s = int2slice( -4, 10, false );
// returns <Slice>

var start = s.start;
// returns 6

var stop = s.stop;
// returns 7

var step = s.step;
// returns 1
```

When `strict` is `true`, the function returns an error object if an input value exceeds index bounds.

```javascript
var s = int2slice( 100, 10, true );
// returns { 'code': 'ERR_SLICE_OUT_OF_BOUNDS' }
```

A returned error object may have one of the following error codes:

- **ERR_SLICE_OUT_OF_BOUNDS**: a slice exceeds index bounds.

s = int2slice( 10, 5, false );

s = int2slice( -10, 5, false );
console.log( '%s', s.toString() );

{{alias}}( value, max, strict )
Converts an integer to a Slice object.

In strict mode, the function returns an error object if an input value
exceeds index bounds.

A returned error object is a plain object having the following properties:

- code: error code.

A returned error object may have one of the following error codes:

- ERR_SLICE_OUT_OF_BOUNDS: a slice exceeds index bounds.

Parameters
----------
value: integer
Input value.

max: integer
Index upper bound (exclusive).

strict: boolean
Boolean indicating whether to enforce strict bounds checking.

Returns
-------
s: Slice|Object
Slice instance (or an error object).

Examples
--------
> var s = {{alias}}( -1, 5, false );
> s.start
4
> s.stop
5
> s.step
1
