The '''grade up''' primitive is used to get the indices of an array that would sort it in ascending order. |
|||
[[Category:Verbs]] |
|||
Since grading is not the same as sorting, a general idiom used to sort arrays is <code>{x(<x)}</code> or other equivalent. |

[[Category:Primitives]] |
|||
Grade primitives generally use a [https://en.wikipedia.org/wiki/Category:Stable_sorts stable sort], which means that an ascending grade may not always be the inverse of a descending grade. |
|||
For numeric arrays: |
|||
<pre> |
|||
<34 -1 0 67 32767 |
|||
1 2 0 3 4</pre> |
|||
Grading of string arrays largely depends upon the implementation. |
|||
For ngn/k(K6), groups by type and sorts each individual group: |
|||
<pre> |
|||
{x(<x)}("xyz";"a";"k";"j";"apl";"bqn") |
|||
("apl" |
|||
"bqn" |
|||
"xyz" |
|||
"a" |
|||
"j" |
|||
"k") |
|||
</pre> |
