Bitwise operators

For bit manipulations the following six operators are provided:

description	operand	example
bitwise AND	&	b001110110 & b0111 = b110
bitwise OR	|	b001110110 | b0101 = b1110111
bitwise exclusive OR	$\wedge$	b001110110 $\wedge$ b0111 = b1110001
left shift	«	b111 « 2 = b11100
right shift	»	b111 » 2 = b1
one's complement (32 bit)	$\sim$	$\sim$b111000 = b111...000111
