What ⦦ means
It is an oblique-angle operator in specialist mathematical notation.
MathML is a web format for writing mathematics. Its operator dictionary lists ⦦ as infix: it sits between the expressions it relates. The surrounding notation supplies its exact operation.
This belongs in mathematical notation; its meaning depends on the notation using it.
Its name alone does not define a universal angle operation.
