Description

The Unicode character U+22DE, known as "Equal To Or Precedes," plays a vital role in mathematical and scientific typography. This symbol is employed to denote the relationship between two quantities in which one quantity is greater than or equal to another within digital text. It is particularly useful for expressing inequalities, such as x ≤ y, where 'x' is less than or equal to 'y,' or x < y, where 'x' is less than 'y.' In addition to its mathematical significance, the U+22DE character also appears in various programming languages and markup languages as a symbol for comparison operators. For instance, it can be used in C++ code as a less-than or equal-to operator (<=) to compare two values. This versatile character contributes significantly to the clarity and precision of digital texts in the domains of mathematics, computer science, and engineering, ensuring that readers understand the intended relationships between different values and quantities.

How to type the symbol on Windows

Hold Alt and type 8926 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+22DE. 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+22DE to binary: 00100010 11011110. 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 10001011 10011110
