Description

U+2339 is the Unicode character code for the APL Functional Symbol Quad Divide. This mathematical symbol represents a specific operation in the programming language APL (A Programming Language), which was developed by Kenneth E. Iverson in 1960s. The primary use of this character is to denote the quadruple division, an operation that divides a number by four raised to the power of another number. In digital text, U+2339 is commonly used within mathematical equations or computer code to indicate this specific operation. Although it has a technical and limited usage context, its presence in APL programming language and mathematics contributes to the richness and diversity of symbols available for expressing complex ideas and calculations.

How to type the symbol on Windows

Hold Alt and type 9017 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+2339. 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+2339 to binary: 00100011 00111001. 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 10001100 10111001
