You could just go ahead an round it to 1 decimal.

I had to do something similar to this, and came across this:

Code:

NumberFormat formatter = new DecimalFormat("#0.0");
double a = 0.1;
double count = Main.cookies.getDouble(p.getName() + ".Cookies");
count += a;
String cookieCount = formatter.format(count);
Main.cookies.set(p.getName() + ".Cookies", cookieCount);
p.sendmessage("You have [" + cookieCount + "] Cookies!");
try {
Main.cookies.save(Main.file1);
} catch (IOException e1) {
e1.printStackTrace();
}

 

I did not want to spoonfeed him so i gave him a link to a site that states pretty much what you wrote.

Thread wasnt marked as solved, i already knew the answer so did not check the stackoverflow and just decided to tell him how, he probably would have copy+pasted from the stackoverflow answer anyway

 

thx to you both for the help
