Excel 201 rounding creating a problem with my macro

I am trying to get the OilTotal cell to change based upon the entry in the OilQuantity cell. I’m sure this has to do with rounding. Can someone help debug my macro or make it easier to read/understand?  See attached file.

Item             Qty                            Unit Price              Total
Cake Mix      27                             \$2.00              \$54.00
Oil (48 oz)      72.00000009             \$2.00              \$2.00

You don't need to be that specific. Try something like this:
``````Select Case Range("OilQuantity").Value
Case Is > 72
Range("OilTotal").Formula = "=OilUnitPrice * 5"
Case Is > 56
Range("OilTotal").Formula = "=OilUnitPrice * 4"
Case Is > 37
Range("OilTotal").Formula = "=OilUnitPrice * 3"
Case Is > 18
Range("OilTotal").Formula = "=OilUnitPrice * 2"
Case Else
Range("OilTotal").Formula = "=OilUnitPrice * 1"
End Select
``````
Note that I'm guessing as to the breakpoints. Also note that with Select Case, the first Case (top to bottom) that's True is the one used.

Here's something I copied from the web. BTW, please don't forget to close this question.

One of the best methods for multiple conditions is the Select Case Statement. It does away with the need for multiple If Statements which can make Excel VBA code very hard to read and decipher. The Select Case Statement has a syntax of:

``````Select Case < Expression to test>

Case

Do something

Case Else

Do something else

End Select
As you can see the Select Case Statement is very similar to the If Statement in that it will only perform some action if/when a condition is met. However, as you will learn, the Select Case is far more flexible. Let's look at the "Select Case" Statement in it's simplest form.

Sub TheSelectCase1()

Select Case Range("A1").Value

Case 100

Range("B1") = 50

End Select

End Sub
Now let us say you need to perform any one of 5 actions depending on the Value of Range A1. If so we could use;

Sub TheSelectCase2()

Select Case Range("A1").Value

Case 100

Range("B1").Value = 50

Case 150

Range("B1").Value = 40

Case 200

Range("B1").Value = 30

Case 350

Range("B1").Value = 20

Case 400

Range("B1").Value = 10

End Select

End Sub
This, in my opinion, is a far better structure and easier to read than an If Statement with multiple ElseIf Statements. If none of the above Conditions were met, nothing would occur, unless we use the optional Case Else Statement, like:

Sub TheSelectCase3()

Select Case Range("A1").Value

Case 100

Range("B1").Value = 50

Case 150

Range("B1").Value = 40

Case 200

Range("B1").Value = 30

Case 350

Range("B1").Value = 20

Case 400

Range("B1").Value = 10

Case Else

Range("B1").Value = 0

End Select

End Sub
So if the value of range A1 is NOT 100,150,200,350 or 400 then place a Value of 0 (zero) in Range B1.

Now while this demonstrates how we can check multiple conditions with the Select Case Statement, what if we want to perform some action if the Range A1 is equal to any one of the Values 100,150,200,350 or 400. If this is the case (no pun intended) we could use:

Sub TheSelectCase4()

Select Case Range("A1").Value

Case 100, 150, 200, 350, 400

Range("B1").Value = Range("A1").Value

Case Else

Range("B1").Value = 0

End Select

End Sub
Let's assume that you only want to perform some action if the range(s) you are checking are between 2 numbers. If this is the case (excuse the pun) then you could use:

Sub TheSelectCase5()

Select Case Range("A1").Value

Case 100 To 500

Range("B1").Value = Range("A1").Value

Case Else

Range("B1").Value = 0

End Select

End Sub
In this instance, if the range A1 contains a number => 100 and =< 500 then cell A1 value will be placed into cell B1.

Now, what about if we needed to check if cell A1 was not only between 100 and 500 but also between 700 and 1000, 1500 and 2000? No problem, with the Select Case you would simply use:

Sub TheSelectCase6()

Select Case Range("A1").Value

Case 100 To 500, 700 To 1000, 1500 To 2000

Range("B1").Value = Range("A1").Value

Case Else

Range("B1").Value = 0

End Select

End Sub
In other words if cell A1 contains a number (eg 600) that does not meet the Case criteria, B1 will equal 0. By-the-way, the limit using a Select Case like this is far from 3 criteria! You can also mix and match the criteria you use in a Select Case Statement, so if you wanted to include some text and/or specific numbers you could use:

Sub TheSelectCase()

Select Case Range("A1").Value

Case 100 To 500, 652, 700 To 1000, 1233, 1500 To 2000, "dog", "cat"

Range("B1").Value = Range("A1").Value

Case Else

Range("B1").Value = 0

End Select

End Sub
Select Case Knows its Alphabet

The last benefit we will look at with the Select Case Statement is how we can use it on text and determine if it lies between other text in an alphabetical sense

Sub TheSelectCase7()

Select Case Range("A1").Text

Case "aardvark" To "elephant"

Range("B1").Value = "it's between"

Case Else

Range("B1").Value = "it's not between"

End Select

End Sub

Thank you for the lesson and documentation.

Here's another way to use Select case that I find useful.
``````Select Case True
Case Range("A1") = 50
MsgBox "OK"
Case Range("B1") = Empty
MsgBox "Please don't forget to close the question"
Case ActiveSheet.UsedRange.Rows.Count > 10000
MsgBox "too many"
End Select
