Apart from your specific example using rates: here's a general description that just shows how to make a square-root calculator. You can extend it to meet your needs. In general, you'll need to follow these steps:

  • Include jquery.js in some HTML page that renders your calculator
  • Have <input type="text" id="mynum"/> fields in your HTML where users input values (or use type="number" etc.). Make sure you use id="...." as the field ID, you'll re-use it later.
  • Have a placeholder to show results, e.g. <div id="result">Calculation result will appear here.</div>. Again, id="...." is used to identify this element so that you can put in values using Javascript.
  • Have some buttons to do calculations, e.g. <input type="button" value="SQRT" onclick="sqrt_stuff();"/>

Next comes the calculation part. The hypothetical above function sqrt_stuff() would then use JQuery to pick up values and paste results; for example:

function sqrt_stuff() {
    // Get user input from field with id "mynum"
    var nr = $('#mynum');
    // Calculate root
    var root = Math.sqrt(nr);
    // Show in div with id "result"
    $('#result').html('The answer is: ' + root);
}
