Convert double into percentage

Issue

How can i convert example 1.07 into 7%, 1.50 into 50%, 2.25 into 125% e.t.c.

My code so far and it's not working:

private static final NumberFormat PERCENTAGE_FORMAT = NumberFormat.getInstance();
PERCENTAGE_FORMAT.setMaximumFractionDigits(0);
PERCENTAGE_FORMAT.format(1.07, "%")

Solution

You can do it like this:

double number = 1.15;

int percentage = (int) Math.round((number - 1) * 100);

System.out.println(percentage + "%"); // Output: 15%

To convert a decimal numbers to its percentage representation as a percentage of 1 you need to subtract 1 first.
