According to Wikipedia when rounding a negative number, you round the absolute number. So by that reasoning, -3.5 would be rounded to -4. But when I use java.lang.Math.round(-3.5) returns -3. Can someone please explain this?
According to the javadoc
Conceptually, you round up. In other words, to the next integer greater than the value and -3 is greater than -3.5, while -4 is less.
