Create a calculator that takes input from the browser. The calculator should display the results using alert.
The calculator should do the basic arithmetic operations.
- Must be able to +, -, / and *
- Must take user input using prompt
- Must be able display the result using alert
- Should use a loop!
- Should handle floats
Implement the advanced calculator:
- Functionality for 'power'
- Functionality for 'square root'
Add these additional settings to the calculator.
Calculate the monthly payment when given the other variables as input.
you need principal, yearly interest rate and the number of payments.
Example: £100,000.00 for- 30 years (360 months) at 6% will yield a payment of just less than £600.00 (£599.55 to be exact`
Calculate the BMI when given the height and weight - the user should be able to choose between the imperial and the metric system
This feature asks the user for four inputs; distance, fuel efficiency (mpg), cost per gallon, speed and it will give you the time and price of your journey.
Example output: "Your trip will take 3.5 hours and cost £255.33.""
Note: For every 1 MPH over 60 MPH, reduce the the MPG by 2 MPG (i.e. a car that normally gets 30 mpg would only get 28 mpg if its speed were 61 mph. Yes this gets silly at high speed where mpg goes to zero or gets negative - how will you handle this?)
When writing code for the Web using JavaScript, there are a great many APIs available. Below is a list of all the interfaces (that is, types of objects) that you may be able to use while developing your Web app or site.
The Window.prompt() displays a dialog with an optional message prompting the user to input some text.
The Window.alert() method displays an alert dialog with the optional specified content and an OK button.
var answer = prompt("What is 5 multipled by 2?");
if (answer == 10) {
alert("Wow! Correct!");
} else {
alert("Wrong!")
}
