| IEEE Floating Point Standard (IEEE 754) " Standard for Binary Arithmetic (ANSI/IEEE Std 754-1985)" or 559: "Binary floating-point arithmetic for microprocessor systems". A , used by many s and s, which defines formats for representing floating-point numbers; representations of special values (e.g. , very small values, ); five , when they occur, and what happens when they do occur; four ; and a set of floating-point operations that will work identically on any conforming system. IEEE 754 specifies four formats for representing floating-point values: single-precision (32-bit), double-precision (64-bit), single-extended precision (80-bit?) and double-extended precision (128-bit). Only 32-bit values are required by the standard, the others are optional though 64-bit is required by standard . [On-line document?] (1997-12-19) |
