示例1: m
REQUIRE((integer_class(100) % integer_class(17)) == 15);
// compound modulus operator
j = -9;
i = 7;
j %= i;
REQUIRE(j == -2);
// move constructor and move assignment
integer_class n = 5;
integer_class m(std::move(n));
i = std::move(m);
// construction of rational_class
// r = rational_class(integer_class(2),3); fails!
r = rational_class(integer_class(2), integer_class(3));
// truncated division
j = integer_class(12) / integer_class(5);
REQUIRE(j == 2);
j = integer_class(-12) / integer_class(5);
REQUIRE(j == -2);
