Data Type Mismatch Error

I'm working on a project to add up the width of rolls (WIDTH ORD) from a given parent roll identified by LENGTH. I only want to analyze parent rolls that have associated pattern numbers that are not integers. i.e. analyze rows with values 5.1, 6.2 but not 5, 6, 7 etc.

I added an excel file with some column values deleted for ease of reading.

Here is my full code

Option Explicit

Sub calc()
    Dim LastRow As Integer
    Dim sum As Integer
    Dim x As Integer
    Dim i As Integer
    
    LastRow = ActiveSheet.UsedRange.Rows.Count
    sum = 0
    x = 1
    
    'Sets column S as integer of column K
    'Subtracts column S from column K and outputs in column T
    'Allows me to distinguish data I want to delete
    For i = 1 To LastRow
        Cells(i, "S").Value = Int(Cells(i, "K"))
        Cells(i, "T").Value = Cells(i, "K").Value - Cells(i, "S").Value
    Next i

    'Deletes rows that contain 0s in column T
    'Deletes data I don't want to analyze
    For i = 1 To LastRow
        If Cells(i, "T").Value = 0 Then
        Rows(i).Delete
        End If
    Next i
    
    'Sums the values in column E for all rows that have the same value in column I
    'Reports sums to column V
    'Sums the width of each pattern roll and reports in column V
    For i = 1 To LastRow
        If Cells(i, "I") = Cells(i + 1, "I") Then
                sum = sum + Cells(i, "E").Value
        Else
            Cells(x, "V").Value = sum + Cells(i, "E").Value
            sum = 0
            x = x + 1
        End If
    Next i

End Sub

I'm getting a mismatch type error at these parts

    For i = 1 To LastRow
        Cells(i, "S").Value = Int(Cells(i, "K"))
        Cells(i, "T").Value = Cells(i, "K").Value - Cells(i, "S").Value
    Next i

        Else
            Cells(x, "V").Value = sum + Cells(i, "E").Value
            sum = 0
            x = x + 1
        End If

Could it be that the Cells.Value data type doesn't match the Int() data type?
In that case I don't know how to change either one of the data types.
Any help would be much appreciated!
