Palindromic Number

Finding the word whether its Palindromic had been discussed in the past.How about numbers? and that without using String or character array?I wrote a program but its rather brut force.i.e. comparing quotient with remainder and reducing the number and repeating till middle one.
Any other better approach?

Hi Capablanca,
how about reducing the original number with it reverse? This should always result in zero (0). If not, you don't have a palindrome.

I think this will increase one additional step.bcos brut force,we are doing the same thing.

you could always cheat...
String s=(new Integer(1881)).toString();
It is sorta covered in the JavaRanch Style Guide.
