Stop DecimalFormat with percentage sign from moving the decimal

Question

Is there a way to prevent a DecimalFormat object from automatically moving the decimal place two places to the right?

This code:

double d = 65.87;
DecimalFormat df1 = new DecimalFormat(" #,##0.00");
DecimalFormat df2 = new DecimalFormat(" #,##0.00 %");
System.out.println(df1.format(d));
System.out.println(df2.format(d));

produces:

65.87
6,587.00 %

But I'd like it to produce:

65.87
65.87 %

Answer 1

Surround your % with single quotes:

DecimalFormat df2 = new DecimalFormat(" #,##0.00 '%'");

Answer 2

By default when you use a % in your format string the value to be formatted will be first multiplied by 100. You can change the multiplier to 1 using the DecimalFormat.setMultiplier() method.

double d = 65.87;
DecimalFormat df2 = new DecimalFormat(" #,##0.00 %");
df2.setMultiplier(1);
System.out.println(df2.format(d));

produces

 65.87 %

Answer 3

This is how I do it:

// your double in percentage:
double percentage = 0.6587;

// how I get the number in as many decimal places as I need:
double doub = (100*10^n*percentage);
System.out.println("TEST:   " + doub/10^n + "%");

Where n is the number of decimal places you need.

I know this isn't the cleanest way but it works.

Hope this helps.
