The '''grade down''' primitive is used to get the indices of an array that would sort it in descending order. |
|||
Since grading is not the same as sorting, a general idiom used to sort arrays is <code>{x(>x)}</code> or other equivalent. |
|||
Grade primitives generally use a [https://en.wikipedia.org/wiki/Category:Stable_sorts stable sort], which means that an descending grade may not always be the inverse of an ascending grade. |
|||
For numeric arrays: |
|||
<pre> |
|||
>34 -1 0 67 32767 |
|||
4 3 0 2 1 |
|||
</pre> |
|||
Grading of string arrays largely depends upon the implementation, as shown in [[grade up]]. |
