The value of x/y is of type Extended, regardless of the types of x and y. For other arithmetic operators, the result is of type Extended whenever at least one operand is a real; otherwise, the result is of type Int64 when at least one operand is of type Int64; otherwise, the result is of type Integer. If an operand’s type is a subrange of an integer type, it is treated as if it were of the integer type. • The value of x div y is the value of x/y rounded in the direction of zero to the nearest integer.

B, where A is the smallest ordinal value in the result set and B is the largest. The following rules apply to <=, >=, =, <>, and in. • X <= Y is True just in case every member of X is a member of Y; Z >= W is equivalent to W <= Z. U = V is True just in case U and V contain exactly the same members; otherwise, U <> V is True. • For an ordinal O and a set S, O in S is True just in case O is a member of S. 4-10 Object Pascal Language Guide Expressions Relational operators Relational operators are used to compare two operands.
