Supplemental Mathematical Operators is a Unicode block containing various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.

Block

Variation sequences

The Supplemental Mathematical Operators block has eight variation sequences defined for standardized variants.^[3] They use (VS01) to denote variant symbols (depending on the font):

Variation sequences

Base character	Base	+VS01	Description
U+2A3C INTERIOR PRODUCT			tall variant with narrow foot
U+2A3D RIGHTHAND INTERIOR PRODUCT			tall variant with narrow foot
U+2A9D SIMILAR OR LESS-THAN			with similar following the slant of the upper leg
U+2A9E SIMILAR OR GREATER-THAN			with similar following the slant of the upper leg
U+2AAC SMALLER THAN OR EQUAL TO			with slanted equal
U+2AAD LARGER THAN OR EQUAL TO			with slanted equal
U+2ACB SUBSET OF ABOVE NOT EQUAL TO			with stroke through bottom members
U+2ACC SUPERSET OF ABOVE NOT EQUAL TO			with stroke through bottom members

History

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