Android Question Set binary numbers to variables in code studio

[arvin]

How can I pass binary numbers to a variable?
like this:

Dim bb as byte
bb=0B110111

but it is not working.

Binary input

Hi, is there any possibility to input in code a binary number. Something like Dim i as Int . . . i=0b110011 As far as I found, hex can be entered by prefix 0x, but 0b doesn't work. Why I need this? I need to use some value as status flag and entering this in hex or decimal may...

Until @Erel implements base-2 (binary) numeric literals, you might have to make do with either:

Dim bb as byte
bb = Bit.ParseInt("110111", 2)

or octal ? which is slightly easier to convert mentally than hexadecimal :

Dim bb as byte
bb = 067    '110 111 (leading 0 of 067 makes it octal rather than decimal) (no I am not joking)

Tbh I thought there was a Bit.FromBinaryString function to match Bit.ToBinaryString, but... apparently not. Easy enough to roll your own, though:

Sub FromBinaryString(BinStr As String) As Int
    Return Bit.ParseInt(BinStr, 2)
End Sub

or if you really, really, really need the leading "0b" to remind you that what follows is binary, then:

Sub FromBinaryString(BinStr As String) As Int
    If BinStr.ToLowerCase.StartsWith("0b") Then
        Return Bit.ParseInt(BinStr.SubString(2), 2)
    Else
        Return Bit.ParseInt(BinStr, 2)
    End If
End Sub
