|
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
