Here are a few ways to round a double in Java to the nearest integer, tenths, hundredths, or thousandths decimal place.
double x = 0.0d; double y = 0.0d; // Double rounded to the nearest integer. y = (int) (x + 0.5); // Double rounded to the nearest tenth. y = ((int) ((x * 10) + 0.5)) / 10; // Double rounded to the nearest hundredth. y = ((int) ((x * 100) + 0.5)) / 100; // Double rounded to the nearest thousandth. y = ((int) ((x * 1000) + 0.5)) / 1000;
