About This Feature

Overview

ATAN is a math and trigonometry function in WPS Spreadsheets that returns the arctangent of a number. It is useful for spreadsheet calculations, angle-related analysis, and formula workflows on Windows.

Core capabilities include:

Enter ATAN( quickly and use syntax prompts while editing formulas.
Use flexible parameters for different calculation scenarios.
Combine the function with nested formulas and cross-sheet references.
Recalculate results automatically when referenced data changes.

System Requirements

Item	Requirement
Operating system	A Windows device that can run WPS Office normally
App version	The latest version of WPS Office is recommended; WPS Spreadsheets supports this function across supported versions
Network	No mandatory internet connection is required for local formula calculation; internet access is needed for download, installation, and account-related actions
Other	You need an editable spreadsheet file and access to WPS Spreadsheets

Download & Installation

Before using the ATAN function, install WPS Office and open WPS Spreadsheets.

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Provides the `ATAN` function for direct spreadsheet cell formulas, with syntax prompts, cross-sheet references, nested calculations, and automatic recalculation.	Excel provides `ATAN(number)` to return the arctangent of a number in radians, and Microsoft also documents converting the result to degrees with `DEGREES` or `180/PI()`.	Google Sheets provides online spreadsheets for formulas, calculations, analysis, collaboration, and automatic updates in a cloud-based workflow.	Notion formulas support numeric properties, math operators, and many built-in functions for database property calculations rather than traditional spreadsheet cells.	Acrobat supports calculated PDF form fields such as sum, product, average, minimum, and maximum for form-processing workflows.
WPS Advantages	Advantage: WPS keeps ATAN entry, references, and recalculation inside a familiar spreadsheet cell workflow on Windows.	Compared with WPS: Excel has an official ATAN reference page with syntax and degree-conversion examples.	Compared with WPS: Google Sheets emphasizes cloud collaboration and spreadsheet analysis, but the reviewed official page does not provide a dedicated ATAN function reference.	Compared with WPS: Notion formulas are designed around database properties instead of cell-based spreadsheet formulas.	Compared with WPS: Acrobat calculations are focused on PDF form fields rather than general spreadsheet function work.

Overall Conclusion: If you want to enter an inverse tangent formula directly in spreadsheet cells and continue working with references, nested formulas, and recalculation, WPS fits a standard spreadsheet workflow well on Windows. Microsoft Excel also provides a complete official function reference, while Google, Notion, and Adobe focus more on collaborative sheets, database formulas, or PDF form calculations.

Use Cases

No.	Scenario	Suitable for	Main need	How ATAN helps
1	Trigonometric value entry	Students and teachers	Need a quick inverse tangent result	Enter `=ATAN(value)` in a cell to calculate the result
2	Angle conversion analysis	Data analysts	Need a radian result before further conversion	Use `ATAN` first, then combine it with other functions
3	Complex formula building	Finance and engineering users	A single function is not enough for the full calculation chain	Nest `ATAN` with other functions
4	Multi-sheet data linkage	General office users	Data is spread across different worksheets	Reference cells from other sheets and let results update automatically
