How does it work in the search window?

Select Create column in the search window toolbar, then select the Arc tangent operation. As said above, you can add one argument to get the arc tangent of the numbers in the selected field, or two arguments to calculate the arc tangent of the given x- coordinates.

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

...

Example 1

This example uses values in a data table generated from the following CSV.

...

from my.upload.sample.data
select split(message, ";", 17) as `-1to1Values`
select float(`-1to1Values`) as `-1to1Values_float`

...

We want to get the arc tangent of all the numbers in the -1to1Values_float column. To do it, we will create a new column using the Arc tangent operation. Let's call the new column arcTangent.

...

Use the operator select... as...  and add the operation syntax to create the new column. These are the valid formats of the Arc tangent operation:

• atan(number)  → Use this expression to get the arc tangent of the values in the given numeric column. 

• atan(number1, number2)  → Use this expression to get the arc tangent of the specified x- and y-coordinates.

Example 1

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, ";", 17) as `-1to1Values`
select float(`-1to1Values`) as `-1to1Values_float`
  select atan(`-1to1Values_float`) as arcTangent

Example 2

You can copy the following LINQ script and try the above example on the demo.ecommerce.data table.

from demo.ecommerce.data
  select atan(-3, 9) as arcTangentCoords
