Java Program to save decimal
Let’s say the value is 0.10705921712947473 and you want to save only the first 3 decimal digits. At first let us declare the values −
double val = 320.0 / 2989.0; BigDecimal big = new BigDecimal(val);
Now, use setScale() and set the parameter as 3 to save 3 decimal places −
big = big.setScale(3, RoundingMode.HALF_DOWN);
Example
import java.math.BigDecimal;
import java.math.RoundingMode;
public class Demo {
public static void main(String[] args) {
double val = 320.0 / 2989.0;
BigDecimal big = new BigDecimal(val);
System.out.println(String.format("Value = %s", val));
// scale
big = big.setScale(3, RoundingMode.HALF_DOWN);
double val2 = big.doubleValue();
System.out.println(String.format("Scaled result = %s", val2));
}
}Output
Value = 0.10705921712947473 Scaled result = 0.107
