Android Question Split integer into bytes

on_min = on_time Mod 100
on_hr = (on_time - on_min) / 100    'the subtraction isn't strictly necessary but it avoids the question about rounding when casting Double to Int

If on_time >= 0 And on_time <= 2400 Then    'because some people differentiate between midnight at start of day, and midnight at end of day
    Dim HHMM As String = on_time
    Do While HHMM.Length < 4
        HHMM = "0" & HHMM
    Loop
    on_hr = HHMM.SubString2(0, 2)
    on_min = HHMM.SubString(2)    'same as .SubString(2, 4)
Else
    Log("invalid time")
End If

Dim XHHMM As String = on_time + 10000    'assuming on_time is 0..2400 then XHHMM will be 10000..12400 ie 5 digits
on_hr = XHHMM.SubString2(1, 3)
on_min = XHHMM.SubString(3, 5)
