≢

Not Match (≢) (sometimes Natch) is the negation of Match. Thus, it returns 0 when its arguments match, and 1 when they do not. Like Match, it is a dyadic primitive function.

Some rendering engines (like Blink, the rendering engine of Chromium based browsers like Chrome, Edge, and Opera) tend to render ≢ as ≡/ if the selected font does not have the ≢ character (U+2262), but does have ≡ (U+2261) and ̸ (U+0338). This issue can be avoided by selecting a font which is more appropriate for APL.
