U+2A70 "⩰" Approximately Equal or Equal To Unicode Character

U+2A70 "⩰" Approximately Equal or Equal To is a mathematical symbol that combines the ideas of approximate equality and exact equality into a single glyph, typically used to denote that two values are either approximately equal or exactly equal to one another. It is part of the Supplemental Mathematical Operators block, where it serves as a higher-level relation for fields such as algebra, analysis, or computer science, allowing for nuanced expressions when a relationship might hold under both strict and loose conditions. Visually, it resembles two wavy lines stacked over two straight lines, merging the tilde-like approximation with the double horizontal bar of equality, and is distinct from the simpler "approximately equal" symbol (U+2248) by explicitly including the possibility of exact equivalence.
