In a nutshell, “&amp; 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). WebA tag already exists with the provided branch name.
