Description

The Unicode character U+22DB represents the "Greater-Than Equal To Or Less-Than" symbol (≥≤), commonly known as the "great than or equal to" and "less than or equal to" symbol. This versatile mathematical symbol is widely used in digital text, particularly within computer programming languages and scientific notation. It serves a crucial role in comparing numerical values and establishing relationships between variables. The U+22DB symbol is often employed in sorting algorithms, data structures, and conditional statements, demonstrating its fundamental importance in information technology and computing systems. While it may not hold any specific cultural or linguistic significance, the "greater than or equal to" and "less than or equal to" symbols are indispensable tools for developers and programmers in creating efficient and effective algorithms.

How to type the symbol on Windows

Hold Alt and type 8923 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+22DB. 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+22DB to binary: 00100010 11011011. 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 10011011
