$bitwise

Bit operations on integers; the language has no bitwise operators of its own.

9 natives. Read-only natives only look things up; the rest change something. Parameter types use the language's names (Types).

and

read-only

$bitwise.and(a: int, b: int) -> int

Perform a bitwise and operation.

Parameter	Type	Meaning
a	int	First argument.
b	int	Second argument.

Returns int: a & b

get_bit

read-only

$bitwise.get_bit(mask: int, index: int, check_index_range: bool, lower_bound: int, upper_bound: int) -> bool

Get a bit from a given bits set. If we check index range and it's out of range, it will just return false.

Parameter	Type	Meaning
mask	int	The bitmask.
index	int	The bit index to set.
check_index_range	bool	Whether we should check range [lower_bound, upper_bound] for the input index.
lower_bound	int	The lower bound for index.
upper_bound	int	The upper bound for index.

Returns bool: The value of the bit. True is 1 and false is 0.

get_set_count

read-only

$bitwise.get_set_count(mask: int) -> int

Count the number of bits set.

Parameter	Type	Meaning
mask	int	The bitmask.

Returns int: The number of bits set.

not

read-only

$bitwise.not(a: int) -> int

Perform a bitwise not operation.

Parameter	Type	Meaning
a	int	Argument.

Returns int: ~a

or

read-only

$bitwise.or(a: int, b: int) -> int

Perform a bitwise or operation.

Parameter	Type	Meaning
a	int	First argument.
b	int	Second argument.

Returns int: a | b

set_bit

read-only

$bitwise.set_bit(mask: int, index: int, value: bool, check_index_range: bool, lower_bound: int, upper_bound: int) -> int

Set a bit in a given bits set and return the bits set. If we check index range and it's out of range, it will just return the input bits set.

Parameter	Type	Meaning
mask	int	The bitmask.
index	int	The bit index to set.
value	bool	The bit value to set. True is 1, and false is 0.
check_index_range	bool	Whether we should check range [lower_bound, upper_bound] for the input index.
lower_bound	int	The lower bound for index.
upper_bound	int	The upper bound for index.

Returns int: The result of bits set.

shift_left

read-only

$bitwise.shift_left(a: int, b: int) -> int

Perform a bitwise shift left operation.

Parameter	Type	Meaning
a	int	First argument.
b	int	Second argument.

Returns int: a << b

shift_right

read-only

$bitwise.shift_right(a: int, b: int) -> int

Perform an UNSIGNED bitwise shift right operation.

Parameter	Type	Meaning
a	int	First argument.
b	int	Second argument.

Returns int: a >> b

xor

read-only

$bitwise.xor(a: int, b: int) -> int

Perform a bitwise xor operation.

Parameter	Type	Meaning
a	int	First argument.
b	int	Second argument.

Returns int: a ^ b
