SENG 560 Programming Assignment 1 - Mike Horbatak

Introduction

This is a NodeJS library that provides methods to compute basic arithmetic. These functions are as followed:

Addition
Subtraction
Multiplication
Division
Square Root
Exponent
Conversion between the various types (octal, hexadecimal, integer, binary).

How to use this library

To install/add this library to your NodeJS application, install the library using the following command.

npm install seng560_assgn_1

Next, within your application, initialize the library with the following code.

const math = require('seng560_assgn_1');

Once initialized, the following functions are available:

Addition

var a = math.addNumbers(1, 3);
// this will compute: 1 + 3 = 4
console.log("The answer is: " + a);

Subraction

var a = math.subractNumbers(4, 2);
// this will compute 4 - 2 = 2
console.log("The answer is: " + a);

Multiplication

var a = math.multiplyNumbers(10, 6);
// this will compute 10 * 6 = 60
console.log("The answer is: " + a);

Division

var a = math.divideNumbers(4, 2);
// this will compute 4 / 2 = 2
console.log("The answer is: " + a);

Square Root

var a = math.squareRoot(9);
// this will compute the square root of 9 = 3
console.log("The answer is: " + a);

Exponent

var a = math.exponentNumber(4,3);
// this will compute 4^3 = 64
console.log("The answer is: " + a);

Number Conversion

var a = math.numberConvert(1100100, 2, 10);
// this will covert 1100100 (binary (base:2)) to 100(int (base:10))
/*
math.numberConvert(a,b,c);
a = the number you want to convert - will accept string and int values
b = the base of the number (a) being converted - e.g. 2(binary), 8(octal), 10(int), 16(hex)
c = the base the number/string will be converted to - e.g. 2(binary), 8(octal), 10(int), 16(hex)
*/
console.log("The answer is: " + a);
