# Function smallerEq

Test whether value x is smaller or equal to y.

The function returns true when x is smaller than y or the relative
difference between x and y is smaller than the configured epsilon. The
function cannot be used to compare values smaller than approximately 2.22e-16.

For matrices, the function is evaluated element wise.
Strings are compared by their numerical value.


## Syntax

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

### Parameters

Parameter | Type | Description
--------- | ---- | -----------
`x` | number &#124; BigNumber &#124; Fraction &#124; boolean &#124; Unit &#124; string &#124; Array &#124; Matrix | First value to compare
`y` | number &#124; BigNumber &#124; Fraction &#124; boolean &#124; Unit &#124; string &#124; Array &#124; Matrix | Second value to compare

### Returns

Type | Description
---- | -----------
boolean &#124; Array &#124; Matrix | Returns true when the x is smaller than y, else returns false


## Examples

```js
math.smaller(1 + 2, 3)        // returns false
math.smallerEq(1 + 2, 3)      // returns true
```
