Description

The Unicode character U+2247 is known as the "Neither Approximately Nor Actually Equal To" symbol. It holds a unique position in digital text, primarily used in mathematics and formal logic to denote an inequality that is neither approximately nor exactly equal to a certain value or expression. Its role is crucial in various fields like engineering, computer science, physics, and economics where precise mathematical representation of conditions and relationships is critical. Though not as widely recognized as other symbols, it's highly valued for its specific application in complex numerical and logical equations. Its significance extends beyond English-speaking cultures, being universally understood due to the nature of mathematics and logic which transcend language barriers. Despite the fact that this character isn't often seen or used in everyday digital communication, it plays a vital role in the technical and scientific spheres where precise mathematical representation is required.

How to type the symbol on Windows

Hold Alt and type 8775 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+2247. 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+2247 to binary: 00100010 01000111. 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 10001001 10000111
