Wrong results from 'or' and 'xor' operators

[Veranika Liaukevich]

Operators 'or' and 'xor' don't work properly on signed integers. For example, 6 or 10 = 14, 6 xor 10 = 12, but…

$ rasql -q 'select 6 or 10 from a' --out string
....
Query result collection has 1 element(s):
  Result element 1: 2

$ rasql -q 'select 6 xor 10 from a' --out string
...
Query result collection has 1 element(s):
  Result element 1: 2
