— the symptom you described means you have a floating result and want it shown with a single digit after the decimal. 's suggestion to use integer division removes the fractional part entirely, so it is not what you want; was right to point at rounding/formatting as the general approach. Two reliable options follow: keep the value numeric (for further math) and round or truncate it, or produce a formatted string for display.

Keep the value numeric (rounded):

Dim a As Integer = 12
Dim b As Integer = 5
Dim result As Decimal = CDec(a) / CDec(b)
Dim roundedOne As Decimal = Decimal.Round(result, 1, MidpointRounding.AwayFromZero)

Truncate (cut, do not round):

Dim truncatedOne As Decimal = Decimal.Truncate(result * CDec(10)) / CDec(10)

Format for display (string, respects current culture so you may see comma or dot):

Dim display As String = FormatNumber(result, 1)

Use the numeric approach when you need to continue calculations; use formatting when the value is only for showing on screen or output. For financial or high-precision work prefer Decimal to Double. For more detail on the VB-format helper and the rounding API see the Microsoft documentation for the FormatNumber function () and Decimal.Round (Decimal.Round).

Look into Math.Round if you want to keep the value as numeric or number.ToString(format) if the result can be a string.
