How to use the bitwise left shift operator (<<) in 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). WebWhere mask indicates which bits should be shifted left, the rest effectively trimmed off before shifting. Ruby will gladly do really ridiculous stuff like 1 << (1 << 16) which produces a number 19,729 digits long. This is also an Integer. oops inheritance in java
