Formatting numbers using DecimalFormat

Question

I am trying to format prices using DecimalFormat, but this isn\'t working for all variations.

DecimalFormat df = new DecimalFormat(\"0.##\")
df.format(7.8)
d         


        

Answer 1

This doesn't seem to be solved by a single formatter. I suggest you use "0.00" format and replace ".00" with an empty string.

public static String myFormat(double number) {
  DecimalFormat df = new DecimalFormat("0.00");
  return df.format(number).replaceAll("\\.00$", "");
}
