Can someone please explain why int (0.4 * 10.0) is 4 yet int ((2.4 - 2.0) * 10.0) is 3?
And then also please explain how to get 4. i.e. Do I really have to do int (System.Math.Round((2.4 - 2.0) * 10.0))?
It’s just so ugly for something that should be so simple.
The double representation of 2.4 – 2.0 is 0.399999999999. When you convert a number to int the decimal part is truncated so 3.999999999 is truncated to 3.
