WebJul 26, 2015 · Bitwise shifts. The last two operators to work with bit masks are the bitwise shifts. Taken a number, they literally shift its bits right (>>) or left (<<). If you have a decimal number, let’s say “1” and you shift it of one position to the left, you’ll have “10”. Another shift and you’ll get “100”. 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).
