Heavy Equals Sign 🟰
Copy & Meaning

A heavy equals sign — representing equality, equivalence, and the fundamental mathematical relationship where two expressions have the same value. The equals sign, invented by Robert Recorde in 1557, is the most used mathematical symbol after numerals themselves. 'Equal' extends far beyond math into justice (equal rights, equal pay), identity (these things are the same), and equivalence (these two things have the same value or effect).

'=' in code means assignment; '==' means equality comparison. Used for mathematical equations, expressions of equality and equivalence, balance and fairness contexts, identity relationships, and any situation where establishing that two things have the same value or status is the central communication goal.
