Convert 2 decimal to integer

georgeliatsos :

I want to convert number 2.55 to 255 in java.

I have tried the following code but I am getting 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?

you have to round that value, and you can use primitives for that.. i.e. use the primitive double instead of the wrapper class Double

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

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