How to remove decimal values from a value of type 'double' in Java

Question

I am invoking a method called "calculateStampDuty", which will return the amount of stamp duty to be paid on a property. The percentage calculation works fine, and returns the correct value of "15000.0". However, I want to display the value to the front end user as just "15000", so just want to remove the decimal and any preceding values thereafter. How can this be done? My code is below:

float HouseValue = 150000; double percentageValue;  percentageValue = calculateStampDuty(10, HouseValue);  private double calculateStampDuty(int PercentageIn, double HouseValueIn){     double test = PercentageIn * HouseValueIn / 100;     return test; } 

I have tried the following:

• Creating a new string which will convert the double value to a string, as per below:

  String newValue = percentageValue.toString();

• I have tried using the 'valueOf' method on the String object, as per below:

  String total2 = String.valueOf(percentageValue);

However, I just cannot get a value with no decimal places. Does anyone know in this example how you would get "15000" instead of "15000.0"?

Thanks

Answer 1

Nice and simple. Add this snippet in whatever you're outputting to:

String.format("%.0f", percentageValue) 

Answer 2

You can convert the double value into a int value. int x = (int) y where y is your double variable. Then, printing x does not give decimal places (15000 instead of 15000.0).
