Decimal format template

Question

I would like to translate 10000000.0intoPREFIX10,000,000.00

Can I find out which template I should pass to DecimalFormat?

NumberFormat numberFormat = new DecimalFormat(...);
numberFormat.format(10000000.0);

Answer 1

new DecimalFormat("PREFIX#,##0.00");

This will always show at least one integer digit (e.g. 0) and use a comma as a group separator.

Answer 2

The pattern for the number will be:, "#,###.00"which means:

• use language-based grouping delimiter
• use language based decimal separator
• always has 2 places after the decimal separator
• have as many digits as needed
