# rather illogically, when BIGINT field is compared to a string,
# the string is converted to an integer, not to a double.
# When some other integer field (not BIGINT) is compared to a string,
# or when the BIGINT is not a field, but an expression, both
# operands are compared as doubles. The latter behavior is correct,
# according to the manual.
