i use vb 6.0

this is my work..

   1.
      Option Explicit
   2.
       
   3.
      Dim Error As Double
   4.
      Dim x As Double
   5.
      Dim y As Double
   6.
      Dim z As Integer
   7.
      Dim eps As Double
   8.
      Dim a As Integer
   9.
      Dim N As Integer
  10.
       
  11.
      Private Sub cmdCalculate_Click()
  12.
       
  13.
      'user input
  14.
       
  15.
      If IsNumeric(txtN) And IsNumeric(txtEps) And IsNumeric(txtX) Then
  16.
      N = txtN.Text
  17.
      a = txtEps.Text
  18.
      x = txtX.Text
  19.
      Else
  20.
          MsgBox "all input must be numeric", vbExclamation, "numeric test"
  21.
          txtN.SetFocus
  22.
      End If
  23.
       
  24.
      'calculate
  25.
       
  26.
      eps = (10 ^ (-a))
  27.
       
  28.
      Do
  29.
          y = x - (x - (N ^ (1 / 3)))
  30.
       
  31.
          Error = Abs(y - x)
  32.
         
  33.
          x = y
  34.
       
  35.
          z = z + 1
  36.
         
  37.
      Loop Until Error < eps
  38.
       
  39.
      'display the result
  40.
      lblDisplay.Caption = "root : " & y & "             iteration : " & z
  41.
       
  42.
      End Sub
  43.
       
  44.
      Private Sub cmdExit_Click()
  45.
      Unload Me
  46.
      End Sub

how to make the answer appear in the lable be in the decimal places user wants.. for example,if they put 3 in the txtEps,then the result is something like 0.123..

Use the Format() function to take a number and return it as a string formatted the way you want. Look up the specifics in your documentation.
