Is the Integer formatter BINARY not implemented?

Note but looks documented as an example:
See Compound operators; for instance &=(compound bitwise and)

The following code gives errors;
static unsigned short receivedBit;
void setup() {
receivedBit = receivedBit & B1111;

void loop() {

After verification

On a spark it’s 0b instead of B

Thanks for the info, but the doc is unclear about that

Did it work for you using the 0b1111? I see what you mean about the doc’s site saying B11110101 in the bitwise and… I don’t know

Yes it is working now, thanks.
… I beleive the doc a cut/paste of the arduino one :slight_smile:

Thanks @rrobinet1 and @Hootie81!

I will test this and send a PR to fix the wrong example afterwards. :wink:

Hi @kennethlimcp
It may be good to add to the doc a description of the integer constants as for Adruino; see:


I have opened an issue for this:
