Vision Posted May 4, 2011 Share Posted May 4, 2011 Hello, is is possible to search in a array for a specific number ? for exsample: the array has 50 values from 11.5 - 2.0 and i want to find the number of array whats 6.0 or the nearest value in range of 6.0 so if there are only arrays with 5.8 and 6.1 he should pick 6.1 as value? hope u understand my problem^^ Link to comment Share on other sites More sharing options...

hannes08 Posted May 4, 2011 Share Posted May 4, 2011 Hi Vision, for an exact search you can use _ArraySearch() If you want a "similar" or "nearest hit" search, you need to write your own function.

jchd Posted May 4, 2011 Share Posted May 4, 2011 Beware of instability inherent to computations done in floating-point representations.

M23 thanks much ! works prfect one additional question: is that possible to say that he cant select a value below the "6" just the neartest above 6 ?

Moderators Melba23 Posted May 4, 2011 Moderators Share Posted May 4, 2011 Vision, is that possible to say that he cant select a value below the "6" just the neartest above 6 ?Just adjust the comparision logic a bit: For $i = 0 To 9 ; Is element greater than or equal to the target value? If $aArray[$i] >= $iTgtValue Then ; So how close is this element? $nDelta = $aArray[$i] - $iTgtValue ; If it is the closest yet If $nDelta < $nTgtDelta Then ; Reset the results $iTgtIndex = $i $nTgtDelta = $nDelta EndIf EndIf Next And note what jchd said about floating point computations - you might not get the value you imagine if there are a couple of very close possibilities. All clear?
