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

 Live Demo

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
