All binary expressions are evaluated as

a) extended if one of the operands is a floating point type (single,
real/double, extended)
b) qword if both are qword
c) int64 if one of them is an int64, or if one is cardinal and the other
is signed and range or overflow checking is on
d) cardinal if both are cardinal
e) longint in all other cases (so word + word is evaluated as longint)
