Need help with datatime calculations

[Portlight]

Jasper Reports uses java to calculate dates, crystal reports looks like you can create an sql query, I have created the same query in the st_proc.
ISSUE: coming up with three different results

code used in st_proc: datediff(S,clstartcalltime,a.cldatetime)/60 as [Response Time], rounds up and does not give the after decimal portion (1.48 minutes) - however this piece of code will need to be removed from the st_proc when I launch the reports. Currently I am merely trying to figure out why I am getting different results.

code used in crystal reports: (DateDiff ("s", {CC_Report_CrewHistory;1.Call Started}, {CC_Report_CrewHistory;1.Crew Filled}))/60 (This is the result that I must match using iReports - preferably without changing the st_proc.

code used in iReport (java) -$F{Crew Filled}.getMinutes()-$F{Call Started}.getMinutes() does not give me a double it returns an int - which rounds - I need to return or somehow cast this to a double - both crew filled and call started are timedate types in the database.

I am including two pics so that you can see the results of each piece of code. Any help is GREATLY appreciated.

This is should do it:

 

Integer.valueOf($F{Crew Filled}.getMinutes()).doubleValue() - Integer.valueOf($F{Call Started}.getMinutes()).doubleValue()
