math.fix(unit, n, valuelessUnit)
```
Parameters #
Parameter | Type | Description
--------- | ---- | -----------
`x` | number | BigNumber | Fraction | Complex | Unit | Array | Matrix | Value to be rounded
`n` | number | BigNumber | Array | Number of decimals Default value: 0.

```js
math.fix(3.2) // returns number 3
math.fix(3.8) // returns number 3
math.fix(-4.2) // returns number -4
math.fix(-4.7) // returns number -4
math.fix(3.12, 1) // returns number 3.1
math.fix(3.18, 1) // returns number 3.1
math.fix(-4.12, 1) // returns number -4.1
math.fix(-4.17, 1) // returns number -4.1
const c = math.complex(3.22, -2.78)
math.fix(c) // returns Complex 3 - 2i
math.fix(c, 1) // returns Complex 3.2 -2.7i
const unit = math.unit('3.241 cm')
const cm = math.unit('cm')
const mm = math.unit('mm')
math.fix(unit, 1, cm) // returns Unit 3.2 cm
math.fix(unit, 1, mm) // returns Unit 32.4 mm
math.fix([3.2, 3.8, -4.7]) // returns Array [3, 3, -4]
math.fix([3.2, 3.8, -4.7], 1) // returns Array [3.2, 3.8, -4.7]
