Tilde Operator With Rising Dots

108/256

⩫ is a specialized mathematical operator whose reading depends on its notation. Unicode links it to , a homothetic (geometric scaling) relation; they are not interchangeable. STIX’s computer-era effort supported technical publishing and math software.

Text symbol

What ⩫ means

Its reading depends on the notation using it.

MathML classifies ⩫ as an infix operator: it sits between expressions. That tells you its position, not its meaning; the notation must define the relation.

STIX sought a shared set of math symbols for publishing, markup, software, and plain text. Unicode/STIX documents from 2000 and 2001 describe that goal.

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.
