Find minimum value in array
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no direct OO equivalent for the $Arr_Min function, because the OO methods emphasize the use of Collections over the use of arrays.
$Arr_Min can be used to find the minimum value in an array. If the minimum value occurs in multiple array elements, $Arr_Min always returns the lowest array element number containing that value.
Syntax
%result = $Arr_Min (array, maxnum)
| %result | A numeric variable that is set to the array element number that contains the indicated minimum value, or it is set to a -1 if the array or maxnum is invalid. |
|---|---|
| array | An array of string, float, or fixed values. This array must be a single dimensional array and must not be an array in an image. |
| maxnum | The highest array element number to check. This argument can be used to limit the search to the first n elements in an array, where n is a positive integer. |
Examples
In the following example:
%FXARRAY IS FIXED ARRAY(5) %FXARRAY(1) = 81 %FXARRAY(2) = 49 %FXARRAY(3) = 121 %FXARRAY(4) = 25 %NUM = $Arr_Min(%FXARRAY)
%NUM is set to 4.
In the following example:
%STARRAY IS STRING LEN 20 ARRAY(5) %STARRAY(1) = 'HOMER' %STARRAY(2) = 'MARGE' %STARRAY(3) = 'KRUSTY' %STARRAY(4) = 'BART' %STARRAY(5) = 'SELMA' %NUM = $Arr_Min(%STARRAY, 3)
%NUM is set to 1.
