Description

The Unicode character U+2A1C, known as the INTEGRAL WITH UNDERBAR (⌋), is a mathematical symbol that serves an essential role in digital text, particularly in the realm of mathematics and computer science. This typographical representation is typically used to denote an integral with an underbar, which signifies an indefinite integral in calculus. The underbar distinguishes it from other mathematical symbols, such as the traditional integral symbol (∫), and indicates a specific type of integration process. While the character does not have any direct cultural or linguistic significance, its importance lies within the context of precise and accurate communication in scientific and technical fields. By leveraging this Unicode character, professionals and scholars can effectively express complex mathematical concepts with clarity and precision.

How to type the symbol on Windows

Hold Alt and type 10780 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+2A1C. 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+2A1C to binary: 00101010 00011100. 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 10101000 10011100
