About This Feature

Overview

The ATAN function in WPS Spreadsheet returns the arctangent of a given number and can be entered directly in a worksheet cell or in the formula bar. It is useful for spreadsheet calculation, data analysis, and formula-based modeling on Windows.

Key capabilities include:

Enter ATAN( to start the function and view syntax guidance while editing.
Use the function directly in a cell or in the formula bar for everyday calculations.
Combine ATAN with nested formulas and cross-worksheet references, with recalculation after data changes.

This function is suitable for math exercises, data models, teaching demos, and spreadsheet tasks that involve angle-related calculations.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Enter `ATAN(` directly in spreadsheet cells for calculation, with syntax guidance, nested formulas, cross-worksheet references, and recalculation when data changes.	Word supports formulas in table cells for calculations and logical comparisons, but the official page describes a document-table workflow rather than a full spreadsheet formula environment.	The official Google Docs page highlights Gemini writing, summarizing, and question-answering features, and does not describe a spreadsheet-style function entry workflow in Docs.	Notion formulas are used in database properties and can combine properties, built-ins, and functions to produce calculated outputs.	Acrobat supports calculated form fields in PDF forms for totals and field interactions, rather than a general spreadsheet formula grid.
WPS Advantages	Advantage: direct spreadsheet cell formula entry for ATAN. Distinct: supports nested formulas and cross-worksheet references in a spreadsheet workflow.	Compared with WPS: Word formulas are more focused on table calculations inside documents, so the function workflow is narrower for spreadsheet-style analysis.	Compared with WPS: the official Docs page emphasizes AI-assisted writing and summaries instead of worksheet-style formula entry.	Compared with WPS: Notion formulas depend on database properties instead of traditional cell-based spreadsheet formulas.	Compared with WPS: Acrobat calculations are designed for PDF form behavior and totals, not for general spreadsheet analysis.

Overall Conclusion
ATAN in WPS fits a direct spreadsheet workflow on Windows, especially when you need cell-based formula entry, nested calculations, and recalculation after data changes. Other products provide calculation-related features in their own contexts, but their official workflows focus on document tables, database properties, or PDF forms rather than spreadsheet cells.
