Unicode Version 17.0
≙
U+2259 "≙" Estimates is a mathematical symbol composed of an equals sign with a small, upward-pointing hat or circumflex accent placed directly above it, visually suggesting a relationship that is approximate rather than exact. This symbol is typically used in mathematics and technical notation to indicate that two values are estimated to be equal, meaning they are close but not necessarily identical due to rounding, measurement uncertainty, or approximation. It provides a concise way to denote approximate equality in equations, proofs, or data comparisons, distinguishing it from the exact equals sign and other approximation symbols like ≈.
