Decimals in quantities

Why are quantities sometimes showing decimals when the counting is done in whole numbers (integers)?

If the signals are all in integer format (whole numbers) – for example 1 signal/circle in Shift View = 1 pcs of a product – it can still happen that Shift View shows hourly or shift quantity as a decimal number. How does that happen?

It happens when a signal is:

• started in the end of one hour and ended in the beginning of another

  

or

• started in one shift and ended in the next one

  

Example 1:

Product A is counted in pieces, 1 signal/circle = 1 pc.

The cycle time of the production is 1 pc/min.

Production of this signal starts at 08:59:30 and ends one minute later, 09:00:30. A part of the signal, meaning a part of the one piece – let's say half – was produced in the end of the hour that starts at 8:00:00 and ends at 09:00:00, and the other half was produced during the next hour, that starts at 09:00:00 and ends at 10:00:00. So the quantity for the first hour now has a 0,5 pcs in the end, so the hour's total produced quantity will show this decimal. Also – the next hour has this decimal quantity in the beginning of it.

Example 2:

Shift A starts at 08:00:00 and ends at 14:00:00.

Shift B starts at 14:00:00 and ends at 20:00:00.

Product ABC is counted in pieces, 1 signal/circle = 1 pc.

The cycle time of the production is 1 pc/min.

A part of the signal, meaning a part of the one piece – let's say half – was produced in the end of shift A (starting the cycle at 13:59:30) and the other half was produced during the next shift – B (ending the cycle at 14:00:30). So the quantity for shift A now has a 0,5 pcs, so the shift's total produced quantity will show this decimal. Also – shift B has this decimal quantity in the beginning of it.
