Modifying an existing rounding rule interval

A rounding rule interval is defined by ranges of values and a precision. The range of values for the interval specifies a minimum and maximum value. Brackets [ ] are used if you want to include the minimum or maximum in the range; parentheses ( ) exclude the value. The precision defines what the value is rounded to (the nearest 0.1 [tenth], 0.5 [half or whole number], 1 [whole number], and so on).

Note:

If your rounding rule intervals are not large enough, you could experience errors when the application tries to round a value that is not found in any interval of the appropriate rounding rule.
