bit operations

def Int.not : Int → Int

Bitwise not, usually accessed via the ~~~ prefix operator.

Interprets the integer as an infinite sequence of bits in two's complement and complements each bit.

Examples:

• ~~~(0 : Int) = -1
• ~~~(1 : Int) = -2
• ~~~(-1 : Int) = 0

def Int.shiftRight : Int → Nat → Int

Bitwise right shift, usually accessed via the >>> operator.

Interprets the integer as an infinite sequence of bits in two's complement and shifts the value to the right.

Examples:

• ( 0b0111 : Int) >>> 1 = 0b0011
• ( 0b1000 : Int) >>> 1 = 0b0100
• (-0b1000 : Int) >>> 1 = -0b0100
• (-0b0111 : Int) >>> 1 = -0b0100
