Apl Functional Symbol Iota Underbar Symbol

⍸ is an APL functional symbol (iota underbar) used in APL code and technical notation.

U+2378

The symbol ⍸ is Unicode character U+2378, named “APL FUNCTIONAL SYMBOL IOTA UNDERBAR.” It’s primarily associated with APL-style programming and notation. You can copy it directly or use its Unicode escapes in many programming environments.

Apl Functional Symbol Iota Underbar Symbol Meaning

⍸ (U+2378) is an APL functional symbol known as “iota underbar.” In APL contexts, “iota” typically relates to generating or indexing sequences, while the underbar modifier indicates a related variant of that behavior. Because this symbol is part of APL’s functional set, it’s most often encountered in APL source code, technical write-ups, and discussions that preserve exact APL glyphs. Outside of APL, ⍸ may appear in documents that reference APL operators explicitly, such as documentation, code snippets, and educational materials where the precise character matters.

Common uses

  • Copying the exact APL glyph into APL code snippets or documentation
  • Typing the symbol in editors that support Unicode to maintain character-accurate examples
  • Using Unicode escape sequences in source code or templates that must remain plain-text
  • Labeling or annotating APL-related concepts in technical blog posts and tutorials
  • Including the character in design systems or UI mockups for developer-facing content
