Double logical and

⩓ marks logical “and,” but its doubled shape does not define an exact operation; follow the notation’s explanation. A 2000 STIX proposal placed it in a shared math-symbol set for scientific publishing; logical use of the single conjunction sign ∧ is documented from 1930.

What ⩓ means

Yes, but the notation determines its exact operation.

A logical conjunction symbol joins statements with “and.” The doubled shape alone does not assign ⩓ a special rule. Follow the author’s definition; do not read it as “and twice” or assume it replaces ∧.

STIX (Scientific and Technical Information eXchange) was a publisher-led project; its 2000 proposal aimed for shared fonts and character encoding across mathematical, scientific, and technical publishing. It lists ⩓ under “Logical ands and ors.”

Why does ⩓ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
