round off 2 decimal places

[racerrunner]

Halo

can someone tell me how to convert a double variable to 2 decimals? I try using the below code but it cannot work.

DecimalFormat df = new DecimalFormat("0.00");

String a = df.format(123.5%11);

double AA = Double.parseDouble(a);



for instance i want AA = 2.50 instead of 2.5. the program keep on giving me 2.5.

I need the data type to be Double but not String.

adding zeros to the end of a double is pointless.

2.5 = 2.50 = 2.500 = 2.500000000000

If you want it to display the trailing zeros, it has to become a string.

Your code here will give you "2.50", but when displaying numbers, leading and trailing zeros are removed, so it must stay as string.

DecimalFormat df = new DecimalFormat("0.00");

String a = df.format(123.5%11);
