Take this example
f displays 55.00 but whats the letter that would dimply display 55?
Code:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim d As Double = 55.0
Debug.WriteLine(d.ToString())
Debug.WriteLine(d.ToString("c"))
Debug.WriteLine(d.ToString("e"))
Debug.WriteLine(d.ToString("f"))
End Sub
End Class
