Bitwise Expressions

Bitwise operators result in a value of the same type as the left operand manipulated at the bit level.

Operator	Function
&	And
|	Or
^	Xor
~	Negate / Invert
»	Shift Right*
«	Shift Left
>|	Rotate Right
|<	Rotate Left

*) For signed data types an arithmetic shift is used. For unsigned data types a logical shift is used.

An arithmetic shift sign-extends the result, which means that positive numbers remain positive and negative numbers remain negative.

A rotate shift takes the bit that is shifted out and puts that into the bit position now freed up by the shift operation.

a := 0b10101010 & 0b10010011    // 0b10000010
b := ~0b11110000                // 0b00001111
c := 0b11100011 >> 1            // 0b01110001
d := 0b00110011 >| 1            // 0b10011001

Note that the negate ~ operator is a unary operator and takes only one operand - the value it acts upon.
