  - Publishing a version of a file
    In order for readers to see a draft created in HCL Connections Docs, or edits made in Docs, a new version of the file must be published. As of August 2015, if a file is being created or edited in Docs for the first time, publishing is set to occur automatically. If a file was previously created or edited in Docs, you must either enable the Publish Automatically command in that file, or publish each new version manually.
  - What if I have a file conflict?
    A person can decide to upload a new version of a file while another person is editing the file online or has saved an online file that is not yet published. The new uploaded version is stored in Files as its own version number, and you are warned of the conflict the next time you try to edit the file from the Files list.
  - Reverting to last version
    When you are editing in HCL Connections™ Docs, if you are not satisfied with the current version of your document, you can revert to the last version that was published. You can choose to save or discard your current edits before you revert to the last version of a document.
  - Viewing a file by using the viewer
    You can view an uploaded document, spreadsheet, presentation, or PDF file while you are working in Files.

    - Using formulas in calculations
      This section provides background information on formulas and functions, and organizes the functions in alphabetical order or by category to make it easy to find related functions.
      - About formulas and functions
        You enter a formula into a sheet to perform a calculation on numbers, text, or other formulas. When you use formulas, your data becomes dynamic.

ATAN2 function

ATAN2 returns the inverse trigonometric tangent of the specified x- and y-coordinates.

Syntax

ATAN2 (x_num,y_num)

This function returns the inverse trigonometric tangent of the specified x- and y-coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). The angle returned is between -pi and pi, excluding -pi.

Example

=ATAN2(1,1) returns 0.785398163397448 (PI/4 radians).

=ATAN2(-1, -1)returns-2.356194490192344 (-3*pi/4 radians).
