I'm not 100% sure about what you're asking.

And please note that I know next to nothing about JSPs.

The basic concept is pretty simple, though - just treat the
number as a 
string, split it using the decimal point as the limiter, and
wrap the 
portion following the decimal in a SUP element. Say you've
got this HTML:

<form name="myForm">
   <input name="myInput"
type="text"/>
</form>

and somebody enters "8.30" into the input.

#  get the value that was entered

var myForm = document.myForm;
var myInput = myForm.myInput;

var myVal = myInput.value;

#  split the value

var parts = myVal.split(".");

#  create new paragraph and new superscript elements:

var newP = document.createElement("p");
var newSup = document.createElement("sup");

#  insert the parts of the text into the appropriate
elements,
#  and the new SUP element into the new P element:

newP.appendChild(parts[0]);
newSup.appendChild(parts[1]);
newP.appendChild(newSup);

# and display it in the page:

myForm.appendChild(newP);

# if you like, hide the original text input:

myForm.myInput.style.display = "none";

This is all purely client-side. There's no change in how you
obtain the 
text input's value and process it server-side.

NB: I prefer if we keep threads that start on the JS list on
the list. 
Then everyone can contribute to and benefit from the
discussion. Thanks!

Since I do not use a Microsoft operating
system or software, and use only plaintext
for email, there is little need for me to do so.
