Unexpected behaviour with Round() function

[JohnAnson]

Hi Gintaras
This code with QM 2.3.0.1:
out Round(0.5 0)
out Round(1.5 0)
out Round(2.5 0)
out Round(3.5 0)
out Round(4.5 0)
out Round(5.5 0)
out Round(6.5 0)
out Round(7.5 0)
out Round(8.5 0)

Produces this output:
0
2
2
4
4
6
6
8
8

Which is not what I was expecting.
Cheers,
John
