Module Module1

Sub Main()

Dim excel As Excel.ApplicationClass = New Excel.ApplicationClass
Dim wb As Excel.WorkbookClass
Dim ws As Excel.Worksheet

wb = excel.Workbooks.Open("C:\Documents and Settings\work\Desktop\ConsoleApplication1\Yang")
wb.Activate()
ws = wb.Worksheets.Add
excel.Visible = True

Dim ran As RandomUniform = New RandomUniform
ran.randomSetSeed(10)

Dim i As Integer
For i = 1 To 10
ws.Cells(i, 3).Value = ran.randomUniform()
Next

ws.Cells(1, 2).Value = excel.WorksheetFunction.Sum(excel.Range("C1:C10"))

End Sub

End Module

'' This is an implementation of the algorithm used in Numerical
' Recipe's ran0 generator. It is the same as MINSTD with an XOR mask
' of 123459876 on the seed.

' The period of this generator is 2^31.

' Note, if you choose a seed of 123459876 it would give a degenerate
' series 0,0,0,0, ... I've made that into an error.

Public Class RandomUniform
Private Const m As Long = 2147483647
Private Const a As Long = 16807

Private Const r As Long = 2836
Private Const mask As Long = 123459876
Private state As Long

Private Function randomGet() As Long
Dim h As Long = state / q
Dim t As Long = a * (state - h * q) - h * r
If t < 0 Then
state = t + m
Else
state = t
End If
Return state
End Function

Public Function randomUniform() As Double
