Description

U+2AB5, the "PRECEDES ABOVE NOT EQUAL TO" character, is a crucial element in digital text representation, specifically within mathematical expressions and computer programming. It serves to express an inequality relationship between two variables, where one value precedes another but does not equal it. This symbol holds particular importance in computational typography due to its role in enhancing readability and precision of mathematical equations, formulas, and algorithms. By clearly indicating the non-equality of values, U+2AB5 helps avoid ambiguity and misunderstanding in digital text. Despite being lesser-known compared to other mathematical symbols, it plays a vital role in ensuring accuracy and efficiency within technical, linguistic, and cultural contexts that rely on mathematical expressions.

How to type the symbol on Windows

Hold Alt and type 10933 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+2AB5. 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+2AB5 to binary: 00101010 10110101. 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 10101010 10110101
