U+2349 "⍉" Apl Functional Symbol Circle Backslash Unicode Character
Unicode Version 17.0
⍉
U+2349 “⍉” Apl Functional Symbol Circle Backslash is a character from the APL programming language encoding, specifically representing the combo circular function that negates or reverses a logical or arithmetic operation, often used to denote a null or zero result in array-based computations. It visually resembles a circle with a diagonal line through it, akin to a no entry sign, and serves as a functional operator for inversion or logical not within APL's distinctive symbolic syntax. Its inclusion in Unicode allows for consistent digital representation across systems, preserving the expressive power of APL code for mathematical and data processing applications.
