Solution

  • 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
