A two-cell form for equality in the Nemeth code.
Also known as: Nemeth equality sign, Braille equals operator
In the Nemeth braille code the equals sign is written as two cells, since a single cell cannot be spared for every mathematical relation.
Denotes equality within the Nemeth code, written as a two-cell sequence.
Contexts: Language and transcription
Uses two cells because mathematics needs far more symbols than sixty-three, so multi-cell sequences are the rule rather than the exception in Nemeth.
Contexts: Language and transcription
Two consecutive cells of raised dots forming a single mathematical sign within one line of the expression.
