Bitwise and ruby
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). http://duoduokou.com/c/66083765666426469430.html
