Integer Rounding <> 0.5

Declare two variables with the values (5.4) and 12.6) and add them together.

Integer Rounding - 0.5

Declare two variables with the values (5.5) and 12.5) and add them together.
Any fractional parts equal to 0.5 are rounded (down or up) to the nearest even number.
Although this type of rounding is unusual it is by design to compensate for a bias that could accumulate when adding a lot of 0.5 fractions.
