I looked at the help file for Math.Round and here's what I found Return Value The whole number nearest parameter d . If d is halfway between two whole numbers one of which by definition is even and the other odd then the even number is returned. Remarks The behavior of this method follows IEEE Standard 754 section 4. This kind of rounding is sometimes called rounding to nearest or banker's rounding. Hope this helps
