## fixed-decimal-point.js
Truncate a number to a fixed decimal point
Using the Math.pow() method, we can truncate a number to a certain decimal point that we provide in the function.

Ex.

const toFixed = (n, fixed) => ~~(Math.pow(10, fixed) * n) / Math.pow(10, fixed);
// Examples
toFixed(25.198726354, 1);       // 25.1
toFixed(25.198726354, 2);       // 25.19
toFixed(25.198726354, 3);       // 25.198

## queue.js
class Queue {
    data = []
    maxSize

    constructor(initialData, maxSize = -1) {
        this.data = Array.isArray(initialData) ? initialData : (typeof initialData == "undefined" ? [] : [initialData])
        this.maxSize = maxSize
    }

    isFull() {
