||
## 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. | ||

{{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 | ||
