Description

Creates a column that returns the base specified raised to the power of an exponent.

How does it work in the search window?

Select Create column in the search window toolbar, then select the Power operation. You need to specify two arguments:

The data type of the values in the new column is integer or float.

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, ";", 17) as numbers,
int(numbers) as numbers_int

In the my.upload.sample.data table, we want to raise the values in the numbers_int column of our table to the Power of 2. Name the column numbers_int_pow_2.

The arguments needed to create the new column are:

• Base - numbers_int column

• Exponent - Click the pencil icon and enter 2

Open

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 of the Power operation:

• pow(number_base, number_exponent)

Example

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