title: Jquery decimal mask for latitude
body: <p>I want to put a decimal mask on a textbox.
  I want the for mat to be 999.99999 (three digits to the left of the '.' and 5 to the right.</p>
  
  <p>I want to allow the negative sign '-' at the start</p>
  
  <p>so we can input -245.45218 for example 
  I tried using this:</p>
  
  <pre><code> $("#latitude").decimalMask("999.99999");
  </code></pre>
  
  <p>But this does not allow the '-' sign to be placed at the begining</p>
  
  <p>I also tried</p>
  
  <pre><code>$("#latitude").decimalMask("#999.99999");
  </code></pre>
  
  <p>But it is not working.</p>
  
  <p>Any help is greatly appreciated</p>
