Logic and Set operators Relation symbols
Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.
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 (\pm), multiplication sign (\times) and obelus (\div), 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 (-).
Block
Variation sequences
The Mathematical Operators block has sixteen variation sequences defined for standardized variants. They use (VS01) to denote variant symbols (depending on the font):
| Base character | Base | +VS01 | Description |
|---|---|---|---|
| U+2205 EMPTY SET | zero with long diagonal stroke overlay form | ||
| U+2229 INTERSECTION | with serifs | ||
| U+222A UNION | with serifs | ||
| U+2268 LESS-THAN BUT NOT EQUAL TO | with vertical stroke | ||
| U+2269 GREATER-THAN BUT NOT EQUAL TO | with vertical stroke | ||
| U+2272 LESS-THAN OR EQUIVALENT TO | following the slant of the lower leg | ||
| U+2273 GREATER-THAN OR EQUIVALENT TO | following the slant of the lower leg | ||
| U+228A SUBSET OF WITH NOT EQUAL TO | with stroke through bottom members | ||
| U+228B SUPERSET OF WITH NOT EQUAL TO | with stroke through bottom members | ||
| U+2293 SQUARE CAP | with serifs | ||
| U+2294 SQUARE CUP | with serifs | ||
| U+2295 CIRCLED PLUS | with white rim | ||
| U+2297 CIRCLED TIMES | with white rim | ||
| U+229C CIRCLED EQUALS | with equal sign touching the circle | ||
| U+22DA LESS-THAN EQUAL TO OR GREATER-THAN | with slanted equal | ||
| U+22DB GREATER-THAN EQUAL TO OR LESS-THAN | with slanted equal |
