Mathematical Operators (Unicode block)

Unicode character block From Wikipedia, the free encyclopedia

This article is about the Unicode block. For operators in mathematics, see Operator (mathematics). For mathematical symbols in Unicode, including other blocks, see Mathematical operators and symbols in Unicode.

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

This article contains special characters. Without proper rendering support, you may see question marks, boxes, or other symbols.

Notably absent are the plus sign (+), greater than sign (>) and less than sign (<), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (±), multiplication sign (×) and obelus (÷), due to them already appearing in the Latin-1 Supplement block, although a distinct minus sign (−) is included, semantically different from the Basic Latin hyphen-minus (-).

Variation sequences

The Mathematical Operators block has sixteen variation sequences defined for standardized variants.[3][4] They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote variant symbols (depending on the font):
