armath.js

arMath.js

arMath.js stands for Arithmetic Math.js, which is a simple library made in JavaScript to perform basic mathematical operations

Setup

First install the package:

npm i armath.js

Then require the package in your project file as belows

const arMath = require("armath.js");

Info

arMath.js provides you with following capbilities -

• Addition of two numbers
• Subtraction of two numbers
• Multiplication of two numbers
• Division of two numbers
• Addition of array of numbers
• Subtraction of array of numbers
• Multiplication of array of numbers
• Division of array of numbers
• Squaring of a number
• Squareroot of a number
• Cubing of a number
• Cuberoot of a number
• Modulus of a number
• Floor Division of a number
• Prime number checker

Let me show you a few examples

Addition

Using arMath.add() function we will be adding 1 and 2, It will throw an error if the input provided isn't a number!

const arMath = require("armath.js");

const output = arMath.add(1,2);
console.log(output);

And in the console we can see the results as below

3.0

Like this you can use arMath.sub(), arMath.multiply(), arMath.divide() as your desired requirement

Addition of an array of numbers

arMath.addArray() is the function we will require for adding the arrays

let me show you a simple example

const arMath = require("armath.js");

const numbers = [0,1,2,3,4,5,6,7,8,9,10]
console.log(arMath.addArray(numbers))

Output will be as below

55.0

Similarly we can use the other functions too - arMath.addArray(), arMath.subArray(), arMath.multiplyArray(), arMath.divideArray(), You just have to pass an array to the functions like the above scenario

Modulus of two numbers

To find the modulus of two numbers use arMath.modulus(a, b) , where a & b are any two numbers You have to pass in two parameters here, i.e, the dividend and the divisor Let me show you the example:

const arMath = require("armath.js");

let output = arMath.modulus(2,4);
console.log(output);

Output will be as below

2

Modulus of an array of numbers

To find the modulus of an array of numbers use arMath.modulusArray(array, num), where num is any number and array should be proper array of numbers or else it will throw an error

Let me show you a basic example

const arMath = require("armath.js");

const array = [1,2,3,4,5]; // An array of numbers
const number = 2 // Any number of your choice
console.log(arMath.modulusArray(array, number));

Output

[ 1, 0, 1, 0, 1 ]

Prime checking

To check if its a prime or not you need to use the isPrime(num) function and pass in any number in place of num

Example

const arMath = require("armath.js");

console.log(arMath.isPrime(2));

Output will be

true

If we pass in any composite number, then output will be

false

Positive checking

To check if a number is positive or not, use isPositive(num) function and pass in a number It will show true if its positive, zero in case of 0 and false in case of negative

Example

const arMath = require("armath.js");

console.log(arMath.isPositive(3));

Output

true

Square & Square Root of a number

To find the square use arMath.square(num) & for square root use arMath.sqrt(num)

const arMath = require("armath.js");

const num1 = 5; // Any number of your choice
const num2 = 49;
console.log(arMath.square(num1)); // Output will be 25
console.log(arMath.sqrt(num2)); // Output will be 7

We can use similar approach for cube/cuberoot ,i.e, arMath.cube(a) & arMath.cbrt(a), where a is any number

Floor Division

To floor divide you need to use arMath.floorDivide()

Example

const arMath = require("armath.js");

console.log(arMath.floorDivide(2,4)); // Replace with any number of your choice

It will give you the result of floor division as the output ,i.e, 0
