ryasmi / round.js

Created February 19, 2013 21:05

Rounds an floating point number to an integer.

	var round = function (value) {
	// {value is some number}
	var multiplier = Math.abs(value) / value;
	var sValue = (value + (0.5 * multiplier)).toString();
	var point = sValue.indexOf(".");
	return parseInt(sValue.substring(0, point === -1 ? sValue.length : point), 10);
	// {returns value rounded}
	};

ryasmi / divide.js

Created February 24, 2013 17:08

Returns the result of a division where the numerator is divided by the denominator. This highlights how division is actually just multiplication.

	var divide = function (numerator, denominator) {
	return numerator * (1 / denominator);
	};

	public static void main(String[] args) throws FileNotFoundException {
	Scanner fScan, cScan = new Scanner(System.in);
	String inFile, outFile, findStr;
	FileInputStream fileInput;
	PrintWriter fileOutput;

ryasmi / ReverseColour.js

Last active December 15, 2015 12:09

Reverses RGB colours.

	var reverseNumber = function (maxValue, value) {
	return (maxValue - 1) - value;
	};
	var hex2Dec = function (hexStr) {
	return parseInt(hexStr, 16);
	};
	var dec2Hex = function (decStr, digits) {
	var hexStr = decStr.toString(16);
	var chars = digits - hexStr.length;
	var count;

ryasmi / bubbleSort.js

Last active December 15, 2015 16:59

Sorting algorithms written in JavaScript for an assignment at Oxford Brookes University for the Discrete Maths module.

	var bubbleSort = function (list) {
	var i, temp;
	var swapped = true;
	var iterations = 0;
	var n = list.length;

	while (swapped) {
	swapped = false;
	for (i = 1; i < n; i += 1) {
	iterations += 1;

ryasmi / StringToArray.js

Last active December 16, 2015 11:09

Turns a string into an array.

	// Using func. https://gist.github.com/ryansmith94/5564105
	func("toArray", function (elemDelimeter, attrDelimeter, fn) {
	var i, elemArray, len;

	elemArray = this.split(elemDelimeter);
	len = elemArray.length;

	for (i = 0; i < len; i += 1) {
	elemArray[i] = elemArray[i].split(attrDelimeter);
	if (fn) {

ryasmi / ReplaceAllInString.js

Last active December 16, 2015 11:09

Replaces all occurrences of a string (x) within a string (this) with another string (y).

	// Using func. https://gist.github.com/ryansmith94/5564105
	func("replaceAll", function (x, y) {
	var self = this;

	while (self.indexOf(x) !== -1) {
	self = self.replace(x, y);
	}

	return self;
	}, String.prototype);

ryasmi / ArrayToObject.js

Last active December 16, 2015 11:09

Converts an array values to an object using an arrays on keys. Source: http://stackoverflow.com/questions/12199051/merge-two-arrays-of-keys-and-values-to-an-object-using-underscore

	// Using func. https://gist.github.com/ryansmith94/5564105
	func("toObject", function (keys, values) {
	var i;
	var len = keys.length;
	var result = {};

	values = values \|\| this;

	for (i = 0; i < len; i += 1) {
	result[keys[i]] = values[i];

ryasmi / Function.js

Last active December 16, 2015 17:19

Things learned in JavaScript and they are good. Sourced mainly from Paul Irish (watched his video a while ago but I wanted to get it down in code).

	// new Function.
	var x = (new Function("return " + data))();

	// (1) Better than using eval.
	var x = eval("(" + data + ")");

ryasmi / func.js

Last active December 17, 2015 06:18

A way to extend functionality using prototypes.

	// A function to create non-enumerable functions in specific scopes.
	var func = (function (defineProp, undefined) {
	"use strict";

	// In older browsers Object.defineProperty is not available.
	// In IE8 Object.defineProperty can only be used on DOM elements.
	var initProp = (!defineProp \|\| !defineProp({}, "ie8Test", {value: false})) ?
	function () {} :
	function (name, scope, write, enumer, config) {
	enumer = (enumer === undefined ? false : enumer);
