U+2A81 "⪁" Less-than or Slanted Equal to with Dot Above Unicode Character
Unicode Version 17.0
⪁
U+2A81 "⪁" Less-than or Slanted Equal to with Dot Above is a mathematical symbol used primarily in formal logic and set theory to denote a relationship of ordering or comparison that includes an extra condition or qualification, such as a specific constraint or a less strict inequality. Its design combines a less-than sign with a slanted equal sign beneath it, while a single dot placed above the symbol adds a nuance that distinguishes it from similar operators like the simple less-than-or-equal-to. This character belongs to the Supplemental Mathematical Operators block and is typically employed in advanced academic texts or technical publications where precise notational distinctions are required.
