Print Integer with 2 decimal places in Java

Question

in my code i use integers multiplied by 100 as decimals (0.1 is 10 etc). Can you help me to format output to show it as decimal?

Answer 1

Based on another answer, using BigDecimal, this also works:

BigDecimal v = BigDecimal.valueOf(10,2);
System.out.println(v.toString());
System.out.println(v.toPlainString());
System.out.println(String.format("%.2f", v));
System.out.printf("%.2f\n",v);

Or even your good old DecimalFormat will work with BigDecimal:

DecimalFormat df = new DecimalFormat("0.00");
System.out.println(df.format(v));
