Query for file version less than 10.0 does not return expected data

Question

I'm trying to build a query for all PCs that have a version of Iexplore.exe in c:\windows\program files\ that is less than 10.0 .  When I run the query it returns no data. When I change 10.0 in the query to 9.9 it returns files with version 10.xxx in
the results.  Its as if it is seeing 10.0 as 1.0.   Is this expected ?
select SMS_R_System.Name, SMS_R_System.ADSiteName, SMS_G_System_SoftwareFile.FileName, SMS_G_System_SoftwareFile.FileVersion from  SMS_R_System inner join SMS_G_System_SoftwareFile on SMS_G_System_SoftwareFile.ResourceID = SMS_R_System.ResourceId where
SMS_G_System_SoftwareFile.FileName = "iexplore.exe" and SMS_G_System_SoftwareFile.FilePath = "C:\\program files\\internet explorer\\" and SMS_G_System_SoftwareFile.FileVersion < "9.9"

Answer 1

It is because the values are not integer, they are a string. And therefore 1 is smaller then 9.
