B.5.PI:5.2 - A familiar calculation produces an unusable figure

A daily report divides total operating cost by completed units. On a day with zero completed units, the software displays an infinity marker. The preparer treats it as normal because it happens regularly. During a handover for pricing the next batch, the preparer tries to explain what price decision that entry supports. The gap becomes apparent through the use, before anyone names a division rule.

An existing mathematical explanation establishes that the quotient has no real-valued result when the denominator is zero. That answer removes a false numerical reading; it does not choose a pricing method. The receiving question now concerns which costs, output and period can support the proposed price. Obtain the appropriate accounting and modeling contribution rather than replace the marker with an invented number.

If the receiver shows that the marker already means “no production”, is never used in pricing, and the pricing calculation uses appropriate separate inputs, the unfamiliar display need not be a defect. The relevant use is already explained. Altering the software solely to remove the unusual value would answer a different question.
