How to get the double value that is only two digit after decimal point.
for example
if
i=348842. double i2=i/60000; tv.setText(String.valueOf(i2)); this code generating 5.81403333.
But I want only 5.81.
So what shoud I do?

format(“%. 2f”) We also can use String formater %2f to round the double to 2 decimal places. However, we can't configure the rounding mode in String.
parseFloat(num).toFixed(2);
By using a button: Select the cells that you want to format. On the Home tab, click Increase Decimal or Decrease Decimal to show more or fewer digits after the decimal point.
4.732 rounded to 2 decimal places would be 4.73 (because it is the nearest number to 2 decimal places). 4.737 rounded to 2 decimal places would be 4.74 (because it would be closer to 4.74). 4.735 is halfway between 4.73 and 4.74, so it is rounded up: 4.735 rounded to 2 decimal places is 4.74.
Use DecimalFormat.
DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation (1.23E4), percentages (12%), and currency amounts ($123). All of these can be localized.
Code snippet -
double i2=i/60000; tv.setText(new DecimalFormat("##.##").format(i2)); Output -
5.81

How about String.format("%.2f", i2)?
