problem with quantity field in an alv while displaying

Hi eveyone,

I have one problem with quantity field in my ALV grid. I have ERFMG & Unit of measure fields in my ALV grid. ERFMG is of type QUAN 13 data type. My problem is while displaying ALV grid, if UOM is Meters, i have to display quantity in 3 decimal places and is UOM is in EA or PCS i have to display quantity field as Integer i.e without any decimal places.

Is there any FM to convert this?

Can anyone help me.
