U+2A85 "⪅" Less-than or Approximate Unicode Character

U+2A85 "⪅" Less-than or Approximate is a mathematical symbol that combines the less-than sign with a tilde, indicating that one value is either less than or approximately equal to another, often used in inequalities to express a relationship that is not strictly exact but close in magnitude. It belongs to the Supplemental Mathematical Operators block and is commonly employed in technical fields like mathematics, physics, and engineering to denote an upper bound that allows for a small margin of approximation, such as when comparing experimental results to theoretical limits. Visually, the symbol features a less-than sign with a curving tilde beneath it, distinguishing it from similar characters like the less-than or equal to sign.
