ALT Codes for Math Symbols: APL Symbols

Below is the complete list of Windows ALT Codes for Math Symbols: APL Symbols, their corresponding HTML entity numeric character references, and when available, their corresponding HTML entity named character references, and Unicode code points.

The programming language APL is distinctive in being symbolic rather than lexical: its primitives are denoted by symbols, not words. These symbols were originally devised as a mathematical notation to describe algorithms. APL programmers often assign informal names when discussing functions and operators (for example, product for ×/) but the core functions and operators provided by the language are denoted by non-textual symbols (from Wikipedia).

If you are new to ALT codes and need detailed instructions on how to use ALT codes in your Microsoft Office documents such as Word, Excel & PowerPoint or applicable Microsoft Windows programs & applications, please read How to Use ALT Codes to Enter Special Characters.
