Rounding errors

Rounding errors are important to show the precision of a measurement. This is important in manufacturing because no measuring device can be 100% accurate.

Using error intervals as part of a quality assurance process allow a manufacturer to ensure their business is efficient.

A manufacturer will have a degree of tolerance (error interval) that they decide is acceptable to them.

If the weight of their product is below their lowest error interval, customers are likely to complain and potentially ask for a refund.

If the weight of the product is higher than their highest error interval, their profit margins decrease as the cost of materials are higher than necessary.
