WebDec 15, 2013 · For example, the bitwise AND of 10110111 and00001101 is 00000101. In a nutshell, “& 0xff” effectively masks the variable so it leaves only the value in the last 8 bits, and ignores all the rest of the bits. It’s seen most in cases like when trying to transform color values from a special format to standard RGB values (which is 8 bits long).

WebMay 5, 2024 · A test sketch shows how the technique works, moving blocks of 8 bits first and then shift the last few bits. This testcode is not faster for shift values smaller than 8 but faster for larger values. If the shift factor is fixed you can write a dedicated shift e.g. inline unsigned long shift17(unsigned long l) - see testcode - motorway patrol uk
