aqString.Compare

I am using the aqString.Compare and it's returning the incorrect result. The code looks like this:   var String1 = "15"; var String2 = "7" var test = aqString.Compare(String1, String2, false)   ...

    As baxatob pointed out,, aqString.Compare does a character comparison of strings.  If you're looking at comparing numeric values to determine if one is less than or greater than another, I would suggest converting the strings to integers and then comparing.

     

    var String1 = "15";
var String2 = "7";

if (aqConvert.StrToInt(String1) < aqConvert.StrToInt(String2)) {
    Log.Message('Well, this didn't work');
}
else { Log.Message('Worked just fine')}

According to documentation aqString.Compare() method uses character codes (ASCII) and performing symbol-by-symbol and finishes once a difference is found.

In your case it finds the difference at first symbol, decides that 1 < 7 - and returns -1 as a result. 

Try to change String1 = "85" and it returns 1. 

 

If you need to compare the length of the strings, you can use aqString.GetLength() method.
