positive pay file displaying incorrect number format for some records in the file.

 we recently started using positive pay file to send the file to the bank.

The file is getting generated properly,but some of the records in the file seems to have the check amount displayed incorrectly.

   ACCNUMBER                    CHECK NUMBER          AMOUNT                        DATE          VENDOR

I 00000000000123457799 000000000000015414 000000000002770973 20110228  ADL006:DELTA AIR LINES, INC.     --CORRECT

the AP check amount for the correct record is 27709.73

the AP check amount for the incorrect record is 1079.9
