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?

we now see that the format specifier "%. 2f" tells the printf method to print a floating point value (the double, x, in this case) with 2 decimal places.
printf("%. 2f", value); The %. 2f syntax tells Java to return your variable (value) with 2 decimal places (.
Numbers are so important in Java that six of the eight primitive data types are numeric types. There are both integer and floating point primitive types. Integer types have no fractional part; floating point types have a fractional part. On paper, integers have no decimal point, and floating point types do.
Using the format() method "%. 2f" denotes 2 decimal places, "%. 3f" denotes 3 decimal places, and so on.
int x = 100;
DecimalFormat df = new DecimalFormat("#.00"); // Set your desired format here.
System.out.println(df.format(x/100.0));
