Equals Colon Symbol Meaning
≕ (equals colon, Unicode U+2255) is a mathematical punctuation-like symbol that represents an equality relationship paired with a colon-style distinction. In written math and technical notation, it’s used to convey a specific variant of “equals” that differs from the plain equals sign (=). Because typographic and semantic meanings can depend on the surrounding context (for example, a chosen notation system in a textbook or typeset document), it’s best to use ≕ when you specifically need this glyph rather than substituting a standard equals sign. When publishing or coding, copying the Unicode character ensures consistent rendering across tools that support it.
