U+2254 "≔" Colon Equals Unicode Character

U+2254 "≔" Colon Equals is a mathematical symbol that represents the operation of assignment or definition, commonly used in computer science and logic to indicate that a value or expression is being assigned to a variable or that one quantity is defined as equal to another. It visually combines a colon and an equals sign, serving as a distinct alternative to the more common ":=" notation found in programming languages like Pascal or pseudocode.
