CInt vs. Math.Round in Visual Basic .NET

Question

What is the difference between:

    Dim a As Integer = CInt(2.2)

and

    Dim a As Integer = Math.Round(2.2)

?

Answer 1

CInt returns an integer but will round the .5 to nearest even number so:

2 = CInt(2.5)
4 = CInt(3.5)

Are both true, which might not be what you want.

Math.Round can be told to round away from zero. But returns a double, so we still need to cast it

3 = CInt(Math.Round(2.5, MidpointRounding.AwayFromZero))
