Mathematical Italic Small Epsilon Symbol
𝜀 is the mathematical italic small epsilon used in formulas and technical notation.
U+1D700
𝜀 (Unicode U+1D700) is a styled epsilon commonly used in mathematics. It’s helpful when you need italic typography that matches math-style text.
Mathematical Italic Small Epsilon Symbol Meaning
𝜀 is the Unicode character called “MATHEMATICAL ITALIC SMALL EPSILON” (U+1D700). Like the Greek letter epsilon, it typically appears in mathematical writing where epsilon variables are used. The “italic” math styling distinguishes it from other epsilon forms (such as the plain epsilon). In practice, you may see 𝜀 used as a variable name or parameter in equations, especially in contexts where typographic styling matters (for example, when mixing text and math). When copying, ensure your font and rendering environment support this specific math italic Unicode character.
Common uses
- •Writing math variables in typed equations or notes
- •Labeling parameters in technical documents and reports
- •Designing mathematical symbols in UI/slide typography
- •Typing math-related posts where consistent math styling matters
- •Programming with Unicode math characters in documentation
