I have a problem with my application output. I looked for some related posts but I couldn't find anything.

I use a method that looks like this:

setPercent(score/max score * 100):

Where both score and max score are double. Whenever I set the score as 29 and the max score as 100, for some reason it outputs 28.99999996.

What I've tried: casting 100 as double, making score and max score as ints.

If you need any additional info. just let me know.

Thanks, zryw141

Refer to http://stackoverflow.com/questions/322749/retain-precision-with-double-in-java – James Jithin Dec 03 '15 at 06:58
In Java, if you want to make avoid this precision issue, your have to try BigDecimal. – Roger Dwan Dec 03 '15 at 07:01
I used the BigDecimal and it worked. I wasn't aware of such issue with precison loss before. Thanks a lot! – zryw141 Dec 03 '15 at 07:29
