  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

When importing data from Excel, data which could be interpreted as numeric in Excel may sometimes be imported with excessive decimals, due to the way Excel stores numbers. This is a quick & dirty fix for this. Add a call to

FixExcelImport ( Self)

in the field definition for any field you're importing into, and it should be cleaned-up.

The rounding (11) and length checks (5) can of course be changed to suit. :-)
