Jump to navigation Jump to search “Sexadecimal” redirects here. Hexadecimal numerals are widely used by computer system designers and programmers, as they provide a more binary option indicator v247-friendly representation of binary-coded values. Each hexadecimal digit represents four binary digits, also known as a nibble, which is half a byte. In mathematics, a subscript is typically used to specify the radix.

In programming, a number of notations are used to support hexadecimal representation, usually involving a prefix or suffix. The prefix 0x is used in C and related languages, which would denote this value by 0x2AF3. Hexadecimal is used in the transfer encoding Base16, in which each byte of the plaintext is broken into two 4-bit values and represented by two hexadecimal digits. In contexts where the base is not clear, hexadecimal numbers can be ambiguous and confused with numbers expressed in other bases. There are several conventions for expressing values unambiguously.

15916 is hexadecimal 159, which is equal to 34510. In Intel-derived assembly languages and Modula-2, hexadecimal is denoted with a suffixed H or h: FFh or 05A3H. For bit vector constants VHDL uses the notation x”5A3″. Verilog represents hexadecimal constants in the form 8’hFF, where 8 is the number of bits in the value and FF is the hexadecimal constant. 16 can also be used to switch the reader and printer of a Common Lisp system to Hexadecimal number representation for reading and printing numbers.
