U+236F "⍯" Apl Functional Symbol Quad Not Equal Unicode Character

U+236F "⍯" Apl Functional Symbol Quad Not Equal is a specialized glyph used in the APL programming language to represent the logical operator for inequality between arrays or values, often within the context of a quad (input/output) environment. It visually combines the shape of a quad, a rectangle resembling an output window, with a slash or negation mark to indicate "not equal," serving as a concise notation in APL's symbolic code for comparing whether two elements are different. This character is part of the APL functional symbols block in Unicode, preserving the language's unique and compact mathematical syntax for array-oriented computations.
