Fomula Character Decimal place issue

Dear Expert,

One of the MIC in inspection plan is a Formula MIC, the value will be calculated as per the values in other MIC.

Decimal place for this formula MIC is restricted to 3 - we can't increae this

Some times during RR for the formal MIC, decimal place will be more than 3, so RR value will not updating for the formula MIC.

So how we can make round off the decimal place here.
