    hey all,

    i have this problem with my java program. i have to limit the number of digits in a long to 10, i have thought of ways to do this such as checking if the number is greater than 999,999,999. would this work?

    any help much appreciated

    You're problem there would be this:

    99.9999999999999 etc would always be smaller than 999,999,999!

    instead of checking the size of try:

    [PHP]if (long.toString().length() < 10)
    proceed;[/PHP]

    Hope this suits you.
