Round up from .5 in a %

Ceiling rounds up no matter if you get .1, .3, .5, .7. or whatever the value is for the decimal.

I need to know how to only round up if you have .5. So for example [number].5 round up.

Anyone know how to do this?

Math.Round(0.5) works as expected.

EDIT

Math.Round(0.5, MidpointRounding.AwayFromZero) rounds up if you're on 0.5

Math.Round(number, MidpointRounding.AwayFromZero);

Details and comparison with the default can be seen on the System.MidpointRounding page.

Math.Round() uses banker's rounding by default, so it will round to the nearest even number when dealing with [number].5. In other words, Math.Round(0.5) is 0, while Math.Round(1.5) is 2. You can make it always round up by saying Math.Round(0.5, MidpointRounding.AwayFromZero);
