(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
Parameters
| i | - | The end index of the range of extents to be multiplied together. |
Return value
If i > 0 is true, return the product of extent(k) for all k in range [0, i), otherwise 1
