casting - How to cast a double to an int in Java by rounding it down?

Question

I need to cast a double to an int in Java, but the numerical value must always round down. i.e. 99.99999999 -> 99

Answer 1

Casting to an int implicitly drops any decimal. No need to call Math.floor() (assuming positive numbers)

Simply typecast with (int), e.g.:

System.out.println((int)(99.9999)); // Prints 99

This being said, it does have a different behavior from Math.floor which rounds towards negative infinity (@Chris Wong)
