title: Knockout Validation min/max validation with commas in value
body: <p>I have the following fields in my ViewModel:</p>
  
  <pre><code>self.agi = ko.observable("")
          .extend({ required: true, min: .01 });
  </code></pre>
  
  <p>But when I enter a value of 1,000 I get the following error:</p>
  
  <blockquote>
    <p>Please enter a value greater than or equal to 0.01.</p>
  </blockquote>
  
  <p>1000 validates properly. How can I make the validation disregard the comma?</p>
