How do I print a double value without scientific notation using Java?

Question

I want to print a double value in Java without exponential form.

double dexp = 12345678;

System.out.println("dexp: "+dexp);

It shows this E notation: 1.2345678E7.

I want it to print it like this: 12345678

What is the best way to prevent this?

Answer 1

You can try it with DecimalFormat. With this class you are very flexible in parsing your numbers.

You can exactly set the pattern you want to use.

In your case for example:

double test = 12345678;

DecimalFormat df = new DecimalFormat("#");

df.setMaximumFractionDigits(0);

System.out.println(df.format(test)); //12345678
