title: Jquery Validation has a serious bug on numeric fields where the first character is a decimal
body: <p>i am using asp.net-mvc3 helpers and the jquery validation plugin (what comes out of the box when you use the templates (Create, Edit, etc . .) and i have a field called MiniPrice that is a dataType  <strong>decimal?</strong></p>
  
  <p>so it validates on the client side that i enter a number in the textbox.</p>
  
  <p>if i enter <strong>1.25</strong> it works fine.  If i enter <strong>0.75</strong> it works fine, but if i enter <strong>.75</strong> it give this validation error:</p>
  
  <p><img src="https://i.stack.imgur.com/j3YGj.png" alt="enter image description here"></p>
  
  <p>why does the jquery unobtrusive validation think <strong>.75</strong> isn't a valid number?</p>
  
  <p>I found <a href="http://bugs.jquery.com/ticket/4135" rel="nofollow noreferrer">this bug that was filed years ago</a> on the jquery core site and it was closed as not a jquery core issue but rather a plugin issue.</p>
