Description

The Unicode character U+22DD is known as the "Greater-Than or Equal To" symbol (≥). It plays a significant role in digital text, particularly within mathematics, computer science, and engineering fields where comparisons between numerical values are prevalent. This symbol is part of a family of comparison operators that includes U+22DC (Not Equal To), U+2234 (Less Than or Equal To), and U+2264 (Less Than). The "Greater-Than or Equal To" operator compares two values, where the result is true if the first value is greater than or equal to the second value. While this symbol is most commonly used in digital text for comparison operations, it can also be utilized in everyday language contexts to illustrate relative size and quantity comparisons, such as "The cake is at least 20 centimeters in diameter."

How to type the symbol on Windows

Hold Alt and type 8925 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+22DD. 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+22DD to binary: 00100010 11011101. 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 10011101
