The specification of java.lang.Math.round() says
* Returns the closest {@code int} to the argument, with ties
* rounding up.
It is not clarified what is "ties rounding up".
I guess that it should correspond to the direction "roundTiesToAway" of
IEEE 754-2008
and to the java.math.RoundingMode.HALF_UP .
They round
+0.5 -> +1
-0.5 -> -1
The current implementation of java.lang.Math.round() rounds
+0.5 -> +1
-0.5 -> 0
"ties rounding up" should match IEEE754 standard and other JDK math class,
shouldn't it ?
