Description

The Unicode character U+2A74, also known as the DOUBLE COLON EQUAL, is a symbol that holds significant importance in digital text communication. It is primarily used in programming languages and mathematical expressions to represent equality or assignment of values between two variables. This character has found its place in various contexts, including computer science, mathematics, and engineering. Despite being less common than other characters like the single colon (U+003A) or the equal sign (U+003D), the DOUBLE COLON EQUAL serves a crucial role in certain domains such as data processing and computer programming. It is often employed to denote that two variables hold identical values, acting as a fundamental element for establishing relationships between elements in algorithms and formulas. In its essence, the DOUBLE COLON EQUAL provides a means of ensuring accuracy and consistency in digital text by enabling users to compare values efficiently and make assignments when necessary. While it may not be widely recognized or utilized across all domains, this character remains an essential tool for those working within specialized fields that require precise mathematical and programming representations.

How to type the symbol on Windows

Hold Alt and type 10868 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+2A74. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+2A74 to binary: 00101010 01110100. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
    11100010 10101001 10110100
