quickly trying this in N9 at least it works... ~ # ~ # oneh=100 ; getcurrent=123 ; timeshundred=$(($getcurrent*$oneh)) ; echo $timeshundred 12300 ~ # So it seems that N900 has different shell... What does it give as an answer there?
/home/user # oneh=100 ; getcurrent=123 ;timeshundred=$(($get current*$oneh)) ; echo $timeshundred 12300 /home/user #
