I have a visual basic code that converts numbers to roman numerals. If I input a decimal, I need the error message to display(I already have it, i think).

I need to remove the rounding ability from the program. How do I do that? Ex: input is 2.83 ; output should be the error message instead of 2 or 3

I received help doing this. But could someone explain why the letter "b" is used? why couldn't I use the name of the input textbox?

Here is the code written out:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim b As Integer

Dim result As String

b = Val(number.Text)

Select Case b

Case 1

result = "I"

Case 2

result = "II"

Case 3

result = "III"

Case 4

result = "IV"

Case 5

result = "V"

Case 6

result = "VI"

Case 7

result = "VII"

Case 8

result = "VIII"

Case 9

result = "IX"

Case 10

result = "X"

Case Else

result = "Not in range 1-10"

End Select

roman.Text = result

End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

number.Text = ""

roman.Text = ""

number.Focus()

End Sub

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click

Me.Close()

End Sub

End Class
