| Parameter | Requirement | Description |
|---|---|---|
| T1, T2,... Tn | Integral Constant | Operation's arguments. |
[Note: The requirements listed in this specification are the ones imposed by the default implementation. See Numeric Metafunction concept for the details on how to provide an implementation for a user-defined numeric type that does not satisfy the Integral Constant requirements. — end note]
For any Integral Constants _c_1,_c_2,... _c_n:
typedef[times](./times.html)<c1,_..._c_n_>::type r;

| | Semantics: |
Equivalent to

typedef[times](./times.html)<c,c3,_..._c_n_>::type r;
