\2246
The "approximately but not actually equal to" symbol (≆) is a mathematical operator used to emphasize that two values are roughly similar but explicitly not exact equivalents. Visually combining an approximation tilde with a crossed-out equals sign, it provides a precise way to state "close, but no cigar" in formal equations. While primarily found in advanced mathematics and physics, you might occasionally spot it in technical discussions where strict logical distinctions are necessary.

In Programming

While rarely used in standard programming code, it frequently appears in mathematical typesetting systems like MathML and LaTeX (often via the unicode-math package) to render complex equations defining strict non-exact approximations.
