Format double with new DecimalFormat("0.#####E0") in Java
Firstly, set the double values −
double d1 = 1.39876; double d2 = 2.39876; double d3 = 0.66920;
Now, format the double values with new DecimalFormat("0.#####E0") −
System.out.println(new DecimalFormat("0.#####E0").format(d1));
System.out.println(new DecimalFormat("0.#####E0").format(d2));
System.out.println(new DecimalFormat("0.#####E0").format(d3));The following is an example −
Example
import java.text.DecimalFormat;
public class Demo {
public static void main(String[] argv) throws Exception {
double d1 = 1.39876;
double d2 = 2.39876;
double d3 = 0.66920;
System.out.println(new DecimalFormat("0.#####E0").format(d1));
System.out.println(new DecimalFormat("0.#####E0").format(d2));
System.out.println(new DecimalFormat("0.#####E0").format(d3));
}
}Output
1.39876E0 2.39876E0 6.692E-1
