How to convert decimal format to number format

When I convert this binary to decimal:

010000010110110001101001001000000100000101101000011011010110010101100100001000000100111101110011011011010110000101101110001000000110001001101001011100100111010001101000011001000110000101110100011001010011101000110001001011010011001100101101001100010011100100111000001101110010000001100011011011110111010101101110011101000111001001111001001110100111001101110101011001000110000101101110

using VB.Net, I get this double number: 1.00695950340148E+115.

I need to format it to be normal number like this:

10069595034014783469636931351646363690636553221072125712116008033168565762469882090200055592025448896479090348155246

How can I do that using PHP or VB.Net?

Public Class Test
    Public Shared Sub Main()

Dim Bin as String = "010000010110110001101001001000000100000101101000011011010110010101100100001000000100111101110011011011010110000101101110001000000110001001101001011100100111010001101000011001000110000101110100011001010011101000110001001011010011001100101101001100010011100100111000001101110010000001100011011011110111010101101110011101000111001001111001001110100111001101110101011001000110000101101110"

Dim dec As Double = Nothing
Dim length As Integer = Len(Bin)
Dim temp As Integer = Nothing
Dim x As Integer = Nothing
        For x = 1 To length
            temp = Val(Mid(Bin, length, 1))
            length = length - 1
            If temp <> "0" Then
                dec += (2 ^ (x - 1))
            End If
        Next
        System.Console.WriteLine("Sum of x and y = " &  dec)
    End Sub
End Class

The output is:

please try with my this method, but I have not verified it whether it correct or not:

and when I tried to use your binary,

  "010000010110110001101001001000000100000101101000011011010110010101100100001000000100111101110011011011010110000101101110001000000110001001101001011100100111010001101000011001000110000101110100011001010011101000110001001011010011001100101101001100010011100100111000001101110010000001100011011011110111010101101110011101000111001001111001001110100111001101110101011001000110000101101110"
