Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices.

# Function bitOr

Bitwise OR two values, `x | y`.
For matrices, the function is evaluated element wise.
For units, the function is evaluated on the lowest print base.


## Syntax

```js
math.bitOr(x, y)
```

### Parameters

Parameter | Type | Description
--------- | ---- | -----------
`x` | Number | BigNumber | Boolean | Array | Matrix | null | First value to or
`y` | Number | BigNumber | Boolean | Array | Matrix | null | Second value to or

### Returns

Type | Description
---- | -----------
Number | BigNumber | Array | Matrix | OR of `x` and `y`


## Examples

```js
math.bitOr(1, 2);               // returns Number 3

math.bitOr([1, 2, 3], 4);       // returns Array [5, 6, 7]
```
