Hyperbolic tangent (tanh)
Returns the hyperbolic tangent of the selected numeric field.
How does it work in the search window?
Select Create column in the search window toolbar, then select the Hyperbolic tangent operation. This operation needs only one argument:
|Number (mandatory)||integer, float|
The data type of the new column is integer.
The examples in this article use values in a data table generated from this 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 operation. Click Toggle Query Editor in the search window toolbar and paste the following LINQ query to save time:
select split(message, ";", 16) as numbers,
int(numbers) as numbers_int
my.upload.sample.data table, let's calculate the hyperbolic tangent of the values column which contains numbers of data type integer. Click Create column and select the Hyperbolic tangent operation. Select the values column as the argument and assign a name to the new column - let's call it simply numbers_int_tanh.
Click Create column and you will see the new tanH column containing float values.
How does it work in LINQ?
Use the operator
as... to apply the Create column operation. These are the valid formats of the operation:
Copy the following LINQ script and use it to replicate the previous example if you have uploaded the file.
