Returns
For any values v1 on the right-hand side and v2 on the
left-hand side:
- A negative integer if the expression
v1 < v2is true. - A positive integer if the expression
v1 > v2is true. - 0 if the expression
v1 == v2is true.
Example
The first v1 for which v1 > v2 is true determines
the result. This could lead to unexpected behaviour.
auto tup1 = tuple(1, 1, 1); auto tup2 = tuple(1, 100, 100); assert(tup1 < tup2); //Only the first result matters for comparison tup1[0] = 2; assert(tup1 > tup2);
