Syntax
Round(expression[, numdecimalplaces])
Round(number,precision)
expression
Use: Required
Data Type: Numeric Expression
Any numeric expression.
numdecimalplaces
Use: Optional
Data Type: Long
The number of places to include after the decimal point.
Return Value
The same data type as expression.
Description
Rounds a given number to a specified number of decimal places.
Rules at a Glance
numdecimalplaces can be any whole number between and 16.
Round follows standard rules for rounding. That is, if the digit in the position to the right of numdecimalplaces is 6 or greater, the digit in the numdecimalplaces position is incremented by 1; if 5, it becomes the nearest even number; otherwise, the digits to the right of numdecimalplaces are dropped.
Programming Tips and Gotchas
Round with a numdecimalplaces set to 2 is equivalent to Format (expression, "#.##").
If expression is a string representation of a numeric value, Round converts it to a numeric value before rounding. However, if expression isn't a string representation of a number, Round generates runtime error 13, "Type mismatch." The IsNumeric function insures that expression is a proper numeric representation before calling Round.
If expression contains fewer decimal places than numdecimalplaces, Round doesn't pad the return value with trailing zeros.
