854-1987 - IEEE Standard for Radix-Independent Floating-Point Arithmetic
Description: This standard generalizes ANSI/IEEE Std 754-1985, IEEE Standard for Binary Floating-Point Arithmetic, to remove dependencies on radix and wordlength. It is believed that, except for a possible conflict with the requirements in 5.6 and 7.2 that unrecognizable decimal input strings signal an exception, and in 6.3 that the sign of zero be preserved in certain conversion operations, any implementation conforming to ANSI/IEEE Std 754-1985 will also conform to this standard. In addition, the definition of logb has been enhanced in the Appendix, and two new functions, conv and nearbyinteger, have been added. This standard defines a family of commercially feasible ways for new systems to perform floating-point arithmetic.
