Function Description Example
bit_count(x, bits) → bigint Counts the number of bits set in x (treated as a signed integer with the specified number of bits) in two's complement: SELECT bit_count(9, 64); -- 2

SELECT bit_count(9, 8); -- 2

SELECT bit_count(-7, 64); -- 62

SELECT bit_count(-7, 8); -- 6

bitwise_and(x, y) → bigint Returns the bitwise AND of x and y in two's complement. N/A
bitwise_not(x) → bigint Returns the bitwise NOT of x in two's complement. N/A
bitwise_or(x, y) → bigint Returns the bitwise OR of x and y in two's complement. N/A
bitwise_xor(x, y) → bigint Returns the bitwise XOR of x and y in two's complement. N/A
