Description

The Unicode character U+2310, also known as the REVERSED NOT SIGN (¬), is a typographical symbol with various applications in digital text. It represents logical negation, inverting the truth value of the expression it precedes. In programming and logic gates, this operator can be used to reverse the outcome of a boolean operation or expression, making it an essential tool for developers and programmers. The REVERSED NOT SIGN is derived from the Latin letter "not" (non) and has been widely adopted across multiple platforms due to its universal recognition and clarity in expressing negation. Despite not being specific to any particular culture or language, this symbol contributes significantly to the precision of digital text and communication within the fields of computing and logic operations.

How to type the symbol on Windows

Hold Alt and type 8976 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+2310. 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+2310 to binary: 00100011 00010000. 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 10001100 10010000
