Numeric

Parameters

  • nExpression
    Specifies the numeric expression whose value is to be rounded.

  • nDecimalPlaces

    If nDecimalPlaces is negative, ROUND( ) returns a whole number containing zeros equal in number to nDecimalPlaces to the left of the decimal point. For example, if nDecimalPlaces is –2, the first and second digits to the left of the decimal point in the value are 0.
