[RESOLVED] [2005] Get value range of variable

Hi all,

I am having a problem. I need to know how to check if a value is equal to plus or minus five million of another value.

For instance

Code:

---

if amount 1 = amount2 +- 5000000 then

---

I know this is not correct, because it assumes you want to subtract 5milli from amount2. I don't actually want to subtract anything from amount2, just see if amount1 falls within that range. For example, if amount1 is 10milli, and amount2 is 13milli, then that is considered a "match" (for the purposes of this question anyway).

I know there's probably something (again) fundamental that I'm missing.

vb Code:

if amount2 > amount1 and amount2 - amount1 <= 5000000 or amount1 > amount2 and amount1 - amount2 <= 5000000 then
      ' amount1 is equal to plus or minus five million of amount2
end if

Code:

---

if Amount1 >= (amount2 - 5000000 ) orelse Amount1 <= (amount2 + 5000000 ) then
'Match

end if

---

eidt: Paul's logic is much better :D

Or if you dont want to type that long line of code over and over again, you can put it in a little function that returns true or false:

Code:

---

    Public Function PlusMinus(ByVal origValue As Integer, ByVal compareValue As Integer)
       
Dim maxDifference As Integer = 5000000 'In this case, it is 5 million

        If compareValue > origValue And compareValue - origValue <= maxDifference _
        Or origValue > compareValue And origValue - compareValue <= maxDifference Then
            Return True
        Else
            Return False
        End If

    End Function

---

Code:

---

        Dim num1 As Long = 13000000
        Dim num2 As Long = 18000000
        Dim num3 As Long = Math.Abs(num1 - num2)
        Const variance As Long = 5000000
        Debug.WriteLine(num3.ToString)
        If num3 <= variance Then
            Debug.WriteLine("in range")
        Else
            Debug.WriteLine("outside range")
        End If
