'Fast VBA function to converst binary string to a Long Integer:

Function BitsToLong&(bits$)
    Dim i&
    Static b() As Byte
    If LenB(bits) > 64 Then Exit Function
    If LenB(bits) = 64 Then
        b = bits
    Else
        b = String$(32 - Len(bits), "0") & bits
    End If
    For i = 2 To 62 Step 2
        BitsToLong = 2 * BitsToLong Or (b(i) Xor 48)
    Next
    If (b(0) Xor 48) Then BitsToLong = BitsToLong Or &H80000000
End Function
