highByte and lowByte removing leading zeros

Using Arduino Networking, Protocols, and Devices

Sorry, that comment should have been removed from the example code after i modified it.

Yes, that is the idea. However, when the code is run, it prints out the following

100111
10000
10000
16

so below is what the code says, what it output, and what i expected;

10000 == 0010011100010000

Serial.println(High, BIN); // OUTPUT - 100111 // expected the first 8 digits of 0010011100010000

Serial.println(Low, BIN); // OUTPUT - 100000 // expected the last 8 digits of 0010011100010000

Serial.println(data_rec, BIN); // OUTPUT - 10000 // expected 0010011100010000 

Serial.println(data_rec); // OUTPUT - 16 // expected 10000

So there was an error in the line

 int data_rec = word(High<<&8, Low);

which i have now changed to

 int data_rec = (High<<8| Low);

and the final output works and gives the correct final integer. However, even then it is ommitting leading zeros with

Serial.println(data_rec, BIN); // OUTPUT - 10011100010000// expected 0010011100010000

so why are leading zeros ommitted and in future how can i stop this?

Thanks
