The Round() function utilizes bankers rounding. When the last significant digit is a 5, it will round to the nearest even number. To instead follow the traditional rule of always rounding a 5 UP add a very small value such as + 0.000001

The Round() function can be used in VBA or in an SQL query.

Examples

Dim intDemo as Integer
intDemo = Round (123.64)
'returns 123
intDemo = Round (123.64, 1)
'returns 123.6
intDemo = Round (2.225, 2)
'returns 2.22
intDemo = Round (2.225 + 0.000001, 2)
'returns 2.23
