Rounding (round)

[ 1 Description ] [ 2 How does it work in the search window? ] [ 3 How does it work in LINQ? ]

Description

Adds a new column that rounds the given number to the nearest integer or, if indicated, to a specified number of decimal places.

Use Floor (floor) if you want to get the largest previous integers, and Ceiling (ceil) to round to the smallest following integers.

How does it work in the search window?

Select Create column in the search window toolbar, then select the Rounding operation. You need to specify at least one argument:

Argument	Data type

Argument	Data type
Number to round ^mandatory	integer, float
Decimal precision	integer

The data type of the values in the new column is integer or float, depending on the selected input data.

Example

The examples in this article use values in a data table generated from the following CSV file.

If you want to try the example for yourself, download the file and upload it to your domain clicking Data upload in the navigation pane. Name the new table my.upload.sample.data and select Current date as Date parsing type. Learn more about uploading data in Uploading log files.

After receiving the confirmation message, you can access the table from the Finder, selecting my → upload → sample → data. When you upload data from a file, all the information is included in a single column called message. To split the values into different columns, you can use the Split (split) operation. Click Toggle Query Editor in the search window toolbar and paste the following LINQ query to save time:

from my.upload.sample.data
select split(message, ";", 16) as numbers,
float(numbers) as numbers_float

In the my.upload.sample.data table, we want to round the values in the numbers_float column of our table to one decimal place. To do it, we will create a new column using the Rounding operation.

The arguments needed to create the new column are:

Number to round - numbers_float column
Decimal precision - Click the pencil icon and enter 1

Click Create column and you will see the following result:

How does it work in LINQ?

Use the operator select... as... and add the operation syntax to create the new column. These are the valid formats for the Rounding operation:

round(number)
round(number, integer_decimals)

Example

You can copy the following LINQ script and try the above example on the my.upload.sample.data table.

from my.upload.sample.data
select split(message, ";", 16) as numbers,
float(numbers) as numbers_float,
round(numbers_float, 1) as numbers_float_rounding
