Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.

The block has sixteen variation sequences defined for standardized variants.[3]

History[edit]

The following Unicode-related documents record the purpose and process of defining specific characters in the Mathematical Operators block:

Version Final code points[a] Count L2 ID WG2 ID Document
1.0.0 U+2200..22F1 242 (to be determined)
L2/01-342 Suignard, Michel (2001-09-10), "T.9", Comments accompanying the US positive vote on the FPDAM 1 to ISO/IEC 10646-1:2001 
3.2 U+22F2..22FF 14 L2/00-119[b] N2191R Whistler, Ken; Freytag, Asmus (2000-04-19), Encoding Additional Mathematical Symbols in Unicode
