Description

U+2AB9 (PRECEDES ABOVE NOT ALMOST EQUAL TO) is a relatively obscure character in the Unicode standard, primarily used in mathematical notation. Its primary role lies in representing an inequality relationship between two expressions in digital text. Specifically, it signifies that the expression preceding this symbol is not almost equal to but greater than the following expression. In terms of its usage, U+2AB9 often appears in technical documents or mathematical texts where precise distinctions need to be made between nearly equivalent values. Despite its limited use and somewhat niche status within the vast Unicode library, this character plays a vital role in ensuring accuracy and clarity in specific contexts.

How to type the symbol on Windows

Hold Alt and type 10937 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+2AB9. 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.

    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+2AB9 to binary: 00101010 10111001. 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 10111001
