Java – convert 2 decimal to integer

I want to convert the number 2.55 to 255.55 in Java

I tried the following code, but I got 254 instead of 255:

final Double tmp = 2.55;
final Double d = tmp * 100;
final Integer i = d.intValue();

What is the correct way to achieve this goal?

Solution

You must round the value, you can use primitives

final double tmp = 2.55;
    final double d = tmp * 100;
    long i = Math.round(d);

    System.out.println("round: "+ i);
