Arrays and their indexs
|
I was wondering if there was a way to grab the index with the highest value in an array? I don't mean the value of the highest index, just the highest index?
#VAR test %array{0,1,0,5,0}
Is there anyway I could get it to return 4? |

That only grabs the length of the array.

If I understand your original question, this is the function you are looking for.
| Quote: |
Syntax: %arrhigh(arrayname)
return the index value of the last element in the array |
#VAR test %array(0,1,0,5,0)
#SH %arrhigh(test)
Output: 4 |

Nope, that gives the number of indexes in the array. I was looking to somehow find the index with the largest value in the array.

You'll have to build your own on that one. It's basically a modified sort function, so it shouldn't be that hard to hammer out.

Perhaps I am completely misunderstanding your question, but I thought you wanted the number of elements.

Then I suppose instead of returning 4, you'd want it to really return the index of 3 with the value of 5?
Ah, you know what. We have misunderstood each other. The first element of an array is at 0 (zero), not 1.
Now I understand your question  Unfortunately, there is no "built-in" way of doing this. |

If you can use lists instead of arrays you can use the %max function.
