Forms :: Uploading Excel File Using Webutil In AIX

When i am uploading data in an excel file to my Forms(Windows) the screen works fine . But when i am uploading the same excel file to my forms in AIX(Where the application is running) the data is wrongly uploaded . The field is a number type and no format mask is set.

E.g. :
Actual data:---------- In Form(Windows)------In Form (AIX)
3101513480750030000 3101513480750030000 3101513480750029800

I am using below code to copy the value

cell_value :=Client_OLE2.get_num_property(cell, 'Value');
COPY(cell_value,'data.field'||k);
