**IEEE-854 Standard**

The main objective of the IEEE-854 standard was to define a standard for floating-point arithmetic without the radix and word length dependencies of the better-known IEEE-754 standard. That is why IEEE-854 is called the IEEE standard for radix-independent floating-point arithmetic. Although the standard specifies only the binary and decimal floating-point arithmetic, it provides sufficient guidelines for those contemplating the implementation of the floating point using any other radix value such as 16 of the hexadecimal number system. This standard, too, specifies four formats including single, single-extended, double and double-extended precision formats.
