Decimal values in 2nd description of TB Codes

Hi

We are working in E9.1 and using fixed batch quantity (with decimal values) for all our BOM and Routings.  We have finalised to populate the 2nd description of time basis code (UDC 30/TB) with exact batch quantity with decimal values, so that product costing will consider standard cost correctly for the complete batch quantity.  Will the system consider the decimal values in UDC 30/TB at the time of routing hours calculation ? Or will it consider only the whole number part and ignores the decimal part ?

Awaiting for your feedback.

Regards
