Approximately Equal with Falling Dots ≒

Semantic identity and intent

Characters to distinguish

• = — Equals Sign
• ≠ — Not Equal To
• < — Less Than

Use ≒ in the right format

Meaning and usage

Expresses the mathematical relation “approximately equal with falling dots” between two objects or quantities.

Use ≒ only when the relation is defined for the objects being compared. For Approximately Equal with Falling Dots (≒), similar-looking relations can differ in algebra, order theory, geometry, and asymptotic analysis.

Pronunciation: approximately equal with falling dots

Formula examples

How to type Approximately Equal with Falling Dots

Windows

Use Character Map or enter U+2252 in a Unicode-aware application.

macOS

Open Character Viewer with Control–Command–Space and search by the symbol name.

Microsoft Word

In an equation, type \fallingdotseq and press Space when Word supports the command.

iPhone and iPad

Copy and paste ≒, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.

Android

Copy and paste ≒, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.

Google Docs

For plain text, paste ≒ or use Insert → Special characters. For structured math, use the equation editor and verify \fallingdotseq.

Excel

Paste ≒ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.

Common mistakes

• Preserve grouping, operator order, and spacing around ≒; Use ≒ only when the relation is defined for the objects being compared. For Approximately Equal with Falling Dots (≒), similar-looking relations can differ in algebra, order theory, geometry, and asymptotic analysis.
• For plain text, copy ≒ as U+2252; for structured equations, use \fallingdotseq in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Approximately Equal with Falling Dots.

When to use ≒

• Use ≒ in plain text when a Unicode character is appropriate and the destination preserves U+2252.
• Use \fallingdotseq in an equation editor when mathematical spacing or structure matters.
• Define the local meaning when Approximately Equal with Falling Dots is used in comparison, optimization with a field-specific convention.

Look-alikes and related characters

• = — Equals Sign
• ≠ — Not Equal To
• < — Less Than

Font and compatibility notes

Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
