## Rounding Values

There are a number of ways of rounding results in SchemeServe, the recommended methods are to use the CEILING function which rounds up and the FLOOR function which rounds down.

It's important to define where the decimal point lands for accurate rounding.

E.g. 101 round up to 200 = CEILING(101/100.0) * 100 = CEILING(1.01) * 100

You can also use the expression Round(number, decimals).

However it is important to understand that the default behaviour of this expression in SchemeServe is to round to the nearest even number.

That means 1.5 and 2.5 both round to two.

The reason for this is that because most numbers tend to be positive rounding away from zero (the standard form of rounding) is statistically less acccurate than rounding to an even number.

If you are looking for financially accurate rounding use RoundUp(number, decimals) as it will always round .5 up.
