Inputbox is not accepting double number VBA excel - vba

Question

I have a declaration like number= InputBox("Number for:", "Number:"), number is declared as Dim number As Double but when I enter a double number, for example 5.4, into the Inputbox and transmit it into a cell, the cell shows me 54, it deletes the point.
How can I fix this?

Answer 1

If you want to detect which settings your Excel uses for the Decimal seperator, try the code below:
MsgBox "Excel uses " & Chr(34) & Application.DecimalSeparator & Chr(34) & " as a decimal seperator"
if you want to change it to ., then use the line below:
Application.DecimalSeparator = "."

Answer 2

Unfortunately, VBA is horrible at handling differences in decimal seprators. In your case, you should probably use a comma (,), instead of a punctuation/dot (.).
Edit: Using the Application.DecimalSeparator method, it now works regardless of regional settings. Be aware though, it seems to cause some issues if you change the comma separator settings for Excel (it seems that VBA somewhat ignores this setting). If you do not change that however, the example should work in all other cas
Sub GetNumberFromInputBox()
Dim val As String
Dim num As Double
'Get input
val = InputBox("Number for:", "Number:")
Debug.Print Application.DecimalSeparator
If IsNumeric(val) Then
'Try to convert to double as usual
num = CDbl(val)
'If the dot is removed automatically, then
'you will se a difference in the length. In
'those cases, replace the dot with a comma,
'before converting to double
If Len(val) <> Len(num) Then
If Application.DecimalSeparator = "," Then
num = CDbl(Replace(val, ".", ","))
Else
num = CDbl(Replace(val, ",", "."))
End If
End If
'Pring the number
Debug.Print "You selected number: " & num
Else
'If its not a number at all, throw an error
Debug.Print "You typed " & val & ", which is not a number"
End If
End Sub
