Orchestrator converts numerical value of a variable to exponential format

Hello,

I am working on an orchestration which reads data from an external data file and creates AP vouchers by matching freight in F4981 table.  It has a data request which reads Invoice Amount (along with some other fields) from the external data file and stores it in a variable called "Gross Amt2".    This value is subsequently fed to "Gross Amount (AG)" field on form W4314A.  If the value is a round number like 2740.00 or 660.00 (where the amount ends with 0 and there are no cents), the orchestration converts it to exponential format like 2.74E+3, 6.6E+2 etc.  The system
