# ROUND

### Description

`ROUND(number[, precision])` returns the value of the given parameter, rounded to the closest whole number or to the given precision\
\
Note that Atfinity uses **bankers rounding** also called **round half to even**, so e.g. 2.5 is rounded to 2, but 3.5 is rounded to 4 (see this [wikipedia article](https://en.wikipedia.org/wiki/Rounding#Rounding_half_to_even) about the topic)

### Example

```
p is Person
ROUND(p.total_fee)
```

This expression returns the total fee that applies to a person, rounded to the whole number. The value for `p.total_fee` could come from another [information field](/guides/glossary/information.md), where an expression with `SUM` is used to calculate the total fee.

### Example with precision

```
p is Person
ROUND(p.total_fee, 2)
```

This expression returns the total fee that applies to a person, rounded to two decimal places. This could, for example, be `290.90`.
