Description

The Unicode character U+2A3B is known as the Multiplication Sign in Triangle (⋯). It represents a mathematical operation, specifically multiplication, and is used in digital text to denote the product of three factors. This symbol has been adopted across various programming languages and digital platforms for consistent representation of this mathematical operation. Although not specific to any particular culture or language, its usage allows for clear communication of complex calculations, particularly in scientific, engineering, and computer science contexts. By employing a triangular shape, the U+2A3B character distinguishes itself from other multiplication symbols, such as the asterisk (*) or the times symbol (×), and enhances readability by visually suggesting repetition or multiplication.

How to type the symbol on Windows

Hold Alt and type 10811 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+2A3B. 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+2A3B to binary: 00101010 00111011. 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 10111011
