The negative result of the bitwise operator

Consider the following statements:

SELECT -5 & -4; – expected: -8, actual: 18446744073709551608
SELECT '-5' | '-4'; – expected: -3, actual: 18446744073709551615
SELECT '5' ^ '-4'; – expected: -7, actual: 18446744073709551609
SELECT ~5; – expected: -6, actual: 18446744073709551610
SELECT -3 > ('5' ^ '-4'); – expected: 1, actual: 0

The result should be negative, but it actually becomes a large value, We think this should be a spillover issue.
