(since C++23)
(exposition only*) |
|
Returns the product of the sizes of extents with index greater than i. The behavior is undefined if i < rank() is false
Parameters
| i | - | an index above which the sizes of corresponding extents will be multiplied together |
Return value
If i + 1 < rank() is true, return the product of extent(k) for all k in range
[
i + 1
,
rank()
)
, otherwise 1
