For matrices, the function is evaluated element wise. ## Syntax ```js math.fix(x) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `x` | number &#124; BigNumber &#124; Fraction &#124; Complex &#124; Array &#124; Matrix | Number to be rounded `n` | number &#124; BigNumber &#124; Array | Number of decimals Default value: 0. ### Returns Type | Description ---- | ----------- number &#124; BigNumber &#124; Fraction &#124; Complex &#124; Array &#124; Matrix | Rounded value ## Examples ```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 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] ``` ## See also [ceil](ceil.md), [floor](floor.md), [round](round.md)
