I have java code that uses double type. I am using a sdk util function to round and restrict the decimal to 2 place. something like:
openCurrentBar=Util.round(localDataSeries.getOpen(paramInt), 2);
highCurrentBar=Util.round(localDataSeries.getHigh(paramInt), 2);
lowCurrentBar=Util.round(localDataSeries.getLow(paramInt), 2);

Open in new window

It does fix the issue temporarily but later in the code these variables show value of 11 digit decimal places again. This happens when they are used for calculation. How can I restrict the decimal paces permanently to 2 digits only such that no matter what happens in the code it does not show more than 2 digits. openCurrentBar should be something like 2365.21 and NOT 2365.213456721309.
