trimming a long in java

sound_wave · 2003-11-25 17:45:28

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.
