Unicode math symbols across web, LaTeX and Word

Nine exact comparison characters, kept aligned across code point, HTML reference, LaTeX command and Microsoft equation input. Each field stays tied to its source.

The reader task

Keep the character and the input syntax together

Symbols that appear related can carry different mathematical roles. This table identifies encoded characters and declared input forms; it does not turn visual resemblance into permission to substitute one symbol for another.

Symbol	Unicode identity	HTML	LaTeX	Microsoft equation input	Example
≈	Almost Equal To `U+2248`	`≈` `≈`	`\approx`	`\approx`	π ≈ 3.14
~	Tilde `U+007E`	`&tilde;` `~`	`\sim`	`\sim`	n ~ 100
≃	Asymptotically Equal To `U+2243`	`&simeq;` `≃`	`\simeq`	`\simeq`	f(n) ≃ g(n)
≅	Approximately Equal To `U+2245`	`&cong;` `≅`	`\cong`	`\cong`	△ABC ≅ △DEF
≉	Not Almost Equal To `U+2249`	`&nap;` `≉`	`\not\approx`	`\not\approx`	1 ≉ 1.5
=	Equals Sign `U+003D`	`=` `=`	`=`	`=`	2 + 2 = 4
≠	Not Equal To `U+2260`	`≠` `≠`	`\ne`	`\ne`	3 ≠ 4
≥	Greater-Than or Equal To `U+2265`	`≥` `≥`	`\ge`	`\ge`	x ≥ 0
≤	Less-Than or Equal To `U+2264`	`≤` `≤`	`\le`	`\le`	x ≤ 10

The visible table and release files are generated from the same nine typed registry records.

Method

Exact identity first

Freeze the nine current registry records.
Preserve each exact Unicode scalar and declared representation.
Map every published field to Unicode, WHATWG, CTAN or Microsoft.
Reconcile nine inputs to nine outputs and hash the release.

Limits

Representation is not interchangeability

This release does not claim that symbols are visually identical, semantically interchangeable, accepted by every parser, rendered by every font or appropriate for every accessibility workflow.
