U+2321
⌡, named BOTTOM HALF INTEGRAL, is a Unicode character (U+2321). It’s useful when you need an integral-like shape that represents only the bottom half in typography or technical layouts. This page helps you copy it and use it correctly in text, code, and design.
Bottom Half Integral Symbol Meaning
⌡ (U+2321) is the Unicode character “BOTTOM HALF INTEGRAL.” It is used in mathematical or technical typography when authors want an integral symbol variant that emphasizes only the lower portion of the integral glyph. Compared to the full integral sign, this character can help fit complex expressions into tight layouts, visually align stacked or combined notation, or create custom symbol constructions in documents and design systems. Because it’s a distinct Unicode character, it’s best used directly rather than as an approximation made from other characters when consistent rendering is important.
Common uses
- •Typesetting specialized math where only the bottom part of an integral symbol is required
- •Building custom mathematical notation in document editors or publishing workflows
- •Designing technical diagrams or formula layouts with constrained spacing
- •Creating consistent UI/UX math glyphs in design systems and dashboards
- •Writing plain-text technical content that relies on Unicode for accurate symbol rendering
