ROUND Function
From Planfix
The ROUND function rounds numbers to the specified number of digits. For example, if column A contains the number 23.7825 and you need to round it to two decimal places, you can use the following formula:
ROUND(A;2)
As a result, you'd get the number 23.78.
Format:
ROUND(number;num_digits)
Examples:
ROUND(A;2)
ROUND({{Task.Number field}};2)
