Definition: hex


(HEXadecimal) Hexadecimal means 16, and the base 16 numbering system is used as a shorthand for representing binary numbers. Each half byte (four bits) is assigned a hex digit or letter as in the following chart with its decimal and binary equivalents. Hex values are identified with an "h" or dollar sign, thus $A7, A7h and A7H all stand for hex A7. See hex chart and hex editor.

 A7
  = decimal 167 (10x16+7x1)
  = binary 10100111 (128+32+4+2+1)

 A000
  = decimal 40,960 (10x4096)
  = binary 1010000000000000 (32768+8192)

Interpreting the Hex
As decimal digits increment by 10, hexadecimal digits increment by 16. Hexadecimal is a shorthand for human readability of binary, which is the intrinsic numbering system in the computer. See binary values.
