how to round DecimalFormat in java (android)

Question

I want to round

0.005 to 0.01

im using this code

DecimalFormat df = new DecimalFormat("0.00");

but the answer keeps getting 0.00 I want only 2 digits on the right with rounding if possible anybody has an idea?

Answer 1

You should add the RoundingMode for the DecimalFormat

double d = 0.005;
DecimalFormat df = new DecimalFormat("0.00");
df.setRoundingMode(RoundingMode.HALF_UP);
System.out.println(df.format(d)); //0.01

Answer 2

For rounding use BigDecimal

BigDecimal decimal = new BigDecimal(number);
decimal = decimal.setScale(2, RoundingMode.HALF_UP);
String result = decimal.toString();
