you have use css text-align: right attribute , javascript mask.

this jquery plugin 1 i've had luck with:

http://digitalbush.com/projects/masked-input-plugin/

example:

<script src="jquery.js" type="text/javascript"></script> <script src="jquery.maskedinput.js" type="text/javascript"></script> <script> $( document ).ready(function() {   // find field id of 'mynum' , mask display 2 digit number   $("#mynum").mask("9.99");   // add mask of 2 digit number class of 'twodigit'   $(".twodigit").mask("9.99");   // old browsers don't class method have run for/each   // loop class name   $(".twodigit").each(function(){      $(this).mask("9.99");   });  }); </script>
