Description

The Unicode character U+2A18, known as the INTEGRAL WITH TIMES SIGN, is a typographical symbol primarily used in mathematical expressions and digital text. It represents the product of two numbers multiplied by the integral sign, which denotes the process of integration in calculus. This character plays a significant role in mathematical notation and communication, particularly within fields such as engineering, physics, and computer science. In terms of cultural, linguistic, or technical context, the INTEGRAL WITH TIMES SIGN is most commonly used in European languages that employ the Latin script, including English. Its precise usage is dependent on the specific language settings and typography conventions employed by the software or text editor being used. Despite its relative obscurity compared to other mathematical symbols, the INTEGRAL WITH TIMES SIGN remains an important tool for clear communication of complex ideas in scientific and technical fields.

How to type the symbol on Windows

Hold Alt and type 10776 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+2A18. 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+2A18 to binary: 00101010 00011000. 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 10011000
