Asymptotically Equal To ≃

(U+2243) is a standard Unicode character that you can copy and paste anywhere text is accepted. This page provides a concise reference with safe tips, internal links, and practical guidance so you can use it reliably across apps and platforms.

What it is and where it’s used: Asymptotically Equal To is part of the Symbols family (block: Mathematical Operators). If you need styled or decorative alternatives, try our Fancy Text tool to generate compatible text that works in most modern interfaces.

History & usage: The symbol has the code point U+2243 and is named ASYMPTOTICALLY EQUAL TO. It appears in math to show that two expressions become close in value as inputs grow large. In math writing, the symbol helps describe limits and approximations without claiming exact equality. In user interfaces, it can mark an estimate or an asymptotic relation in formulas shown to users. The usage_atoms state that common math symbols indicate operations or comparisons in formulas and user interfaces. This makes U+2243 a useful sign for readers who follow a flow from exact to approximate results. It is part of the common symbols used across math texts and schemes. Over time, readers learn to interpret it as a near match rather than a strict equality. The symbol does not replace exact symbols but complements them when precision is less critical. In simple notes, it guides readers toward the idea of asymptotic similarity and trends.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+2243 in many development tools or editors. Some operating systems provide a character viewer or input palette that lets you search by name or code and insert the glyph into documents.

Display and fallback: if you see an empty box (tofu) or a placeholder rectangle, the active font might not include this codepoint. Switching to a font with broader Unicode coverage or using a fallback font usually fixes the issue. On the web, ensure the page’s font stack includes a general‑purpose fallback.

How to type / insert

Fast copy: click the Copy button near the top of this page.

By codepoint: in many editors and IDEs, you can insert via the Unicode code U+2243 or a built‑in character picker.

HTML: use the numeric entity ≃ (hex) or ≃ (decimal) when an HTML entity is needed.

Compatibility & troubleshooting

Font support: if the symbol does not render, the current font likely lacks this codepoint. Choose a font with broad Unicode coverage or allow a fallback font.

Web pages: ensure your CSS font stack includes a general fallback; avoid relying on images for common symbols to preserve accessibility and copyability.
