That is, the marginal cost of an additional user is essentially zero for a sizeable number of users, but then marginal cost grows rapidly in the number of users.
So specifying a -m128bit-long-double will align "long double" to a 16-byte boundary by padding the "long double" with an additional 32-bit zero.
因此指定一个- m 128bit - long - double会将“long double”按照16字节边界进行对齐，它会为“long double”填充32位的0。

Now suppose that you want your Data View to include only current products where the units on order equals zero, so that you can decide whether to order additional units.
