U+2A89 "⪉" Less-than and Not Approximate Unicode Character
Unicode Version 17.0
⪉
U+2A89 "⪉" Less-than and Not Approximate is a mathematical symbol used primarily in formal logic, set theory, and advanced algebra to denote a strict ordering relationship where one value is less than another while explicitly asserting that the two are not approximately equal. This character combines the less-than sign with a negation bar through the approximation symbol, serving as a precise operator in contexts where distinguishing between exact inequality and approximate equivalence is necessary, such as in the study of limits, inequalities with real numbers, or when comparing values that might otherwise be considered close but not identical.
