Example: vba bits to byte

'Extremely fast VBA function to convert a binary string to a Byte:

Function BitsToByte(bits$) As Byte
    Dim i&
    Static b() As Byte
    If LenB(bits) > 16 Then Exit Function
    If LenB(bits) = 16 Then
        b = bits
    Else
        b = String$(8 - Len(bits), "0") & bits
    End If
    For i = 0 To 14 Step 2
        BitsToByte = 2 * BitsToByte Or (b(i) Xor 48)
    Next
End Function


'Example:

MsgBox BitsToByte("00001100")		'<--displays: 12
MsgBox BitsToByte("10000001")		'<--displays: 129
