Interactive Design II – Week 4

1 Comment

Session 1: Today we will begin demonstrations for the Simple JS Calculator Web Application assigned on week 3. During studio time you will be expected to prepare for the JS Calculator milestones described below under session 2.

Google's Calculator

Session 2: Today we will continue our discussion on JavaScript and demonstrate adding functionality to the JS Calculator Web Application. This will including looking at the JavaScript Math object.

Math is a built-in object that has properties and methods for mathematical constants and functions. Not a function object. Unlike the other global objects, Math is not a constructor. All properties and methods of Math are static. You refer to the constant pi as Math.PI and you call the sine function as Math.sin(x), where x is the method’s argument. Constants are defined with the full precision of real numbers in JavaScript. –MDN

During studio time please have the following milestones prepared for feedback.

2. A minimum of four JavaScript functions must be implemented
3. Several alternative functions must be in preparation

    This website shows how to round up numbers when having a rounding number calculator so you don’t get the long string of numbers if you don’t want to have so many spots after the decimal. I thought this could be useful considering how usually people just round up so many places unless they need a very accurate number.

    This website had a lot of interesting uses for creating a calculator for different functions. I didn’t think to make a calculator for things such as a calorie countering or body mass indexing but it makes sense considering if you can do it on a regular calculator you can calculate it with a code.

    I found this shipping calculator to be a useful website tool. It is annoying how on most websites you have to get to the complete checkout page before they tell you your shipping total and think this could be utilized more often.
