The RoundingOption property sets or returns the rounding option to be used when the ValueToString method in the associated INumberFormat interface formats numbers.

The settings for RoundingOption are:

Setting	Description
esriRoundNumberOfDecimals	(Default) Numbers are rounded to the number of decimal places defined in the RoundingValue property. If ZeroPad is also set True, decimal zeros are appended at the right up to the number of places indicated in the RoundingValue property.
esriRoundNumberOfSignificantDigits	Numbers are rounded to the number of significant digits indicated in the RoundingValue property. To format numbers and express significant zeros at the right of the decimal, set ZeroPad True. For example, the number 12.0345 in 8 significant digits is the number 12.034500. In order to express the rightmost significant zeros, ZeroPad should be set True. With ZeroPad set False, the formatted number would be 12.0345.
