(HEXadecimal) Hexadecimal means 16. The base 16 numbering system is used as a shorthand for representing binary numbers. Each half byte (four bits) is assigned a hex digit as shown in the following chart with its decimal and binary equivalents. Hex values are identified with an "h" or dollar sign, thus $3E0, 3E0h and 3E0H all stand for the hex humber 3E0. See hex chart and hex editor.
How to Interpret the Hex
As decimal digits increment by 10, hex digits increment by 16. Two hex digits make up one byte; for example, A7 is equivalent to one byte containing the binary number 10100111, or 167 in decimal. A is 10, thus 160 (10x16) plus 7 (7x1). The hex number A000 (pronounced "A thousand") is 40,960 in decimal (10x4096).
