/**

|
* Round a value towards zero.
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.fix(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* 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]
|
|
*

* ceil, floor, round
|
|
*
|
|
* @param {number | BigNumber | Fraction | Complex | Array | Matrix} x Number to be rounded
