Floating point operations

IEEE arithmetic

This subtopic provides the details of floating point representation, the environment, and exception handling. Most users need not be concerned with the details of the floating point environment.


NOTE: Programs ported from pre-System V Release 4 environments will now proceed using computations with diagnostic values or floating point ``infinities.''


NOTE: The floating point subsystems of the Intel386(TM) microprocessor are based on the Standard for Binary Floating-Point Arithmetic, ANSI/IEEE Standard 754-1985. For more information about this standard, write to IEEE Service Center, 445 Hoes Lane, Piscataway, NJ, 08854, or call (201) 981-0060
