VBA To Round Amount In Column C

I thought it would be simple code. I have column C with amount such as

C1 : 3712.76
C2 : 277.91

When VBA runs, i want value to be rounded to display 3712 and 278 in C1 and C2 respectively.

Code:
Sub RoundC()
Dim N As Long, v As Variant, I As Long
Dim wf As WorksheetFunction
Set wf = Application.WorksheetFunction
N = Cells(Rows.Count, "C").End(xlUp).Row
For I = 1 To N
v = Cells(I, "C").Value
If IsNumeric(v) Then
Cells(I, "C").Value = wf.Round(v, 0)
End If
Next End Sub

This code working, but it end up value to 3712.00 instead of 3712 only. I do not want cell to display additional zero's.

what I am making error here?
