title: Round every textbox to 2 decimal places
body: <p>This is probably really simple, but for the life of me I can't work out how to do it. So here goes: I have a large form with lots of text boxes, which are all currency based and so need to be rounded off to 2 decimal places. The values of these textboxes are all generated dynamically by some JavaScript functions I wrote, and I can use <code>.toFixed(2);</code> to round them up/down to 2 decimal places. However, it gets tiring and repetitive to have to put this after working out each value of each textbox. How could I write a simple piece of JavaScript (can be jQuery) to target all the textboxes and round them ALL to 2 decimal places?</p>
  
  <p>Thanks for any help :)</p>
  
  <p>P.S Sorry for the lack of any code, but there isn't really any to show, as its all locked up in big functions. But here's what I'm essentially doing:</p>
  
  <pre><code>function workOutSomeVal() {
      // lots of code to work out values and stuff
      var finalValue = some mathematical equation to work out value;
      var anotherValue = a different value;
      $(".some-textbox").val((finalValue).toFixed(2));
      $(".another-textbox").val((anotherValue).toFixed(2));
  } // my question is, how could I get rid of .toFixed(2) and put in a generic statement somewhere to target all the textboxes?
  </code></pre>
