Issue Details

When I input an array of string elements into the Array Max & Min Function , I do not get the desired maximum or minimum value. 

Solution

String values in LabVIEW are compared according to the values of the ASCII character codes . 
Therefore, they compare those values from left to right, and not based on the numeric values. 

For instance, if you compare a large value with extra leading zeroes as a string, LabVIEW will consider it smaller than a value that has no leading zeroes. 
(i.e. 1000 > 01001)

If you would like to compare the strings according to their numeric values, you must convert the string into a numeric value first.
