From cppreference.com
constexpr std::size_t /*fwd-prod-of-extents*/( rank_type i ) const noexcept; |
(since C++23) (exposition only*) |
|
Returns the product of the sizes of extents with index less than i. The behavior is undefined if i <= rank() is false.
[edit] Parameters
i | - | The end index of the range of extents to be multiplied together. |
[edit] Return value
If i > 0 is true, return the product of extent
(k) for all k
in range [
0,
i)
, otherwise 1.
