摘要

作者建议每台有浮点加减运算的计算机都应该有PSW控制的舍入功能。应该包括你的目录。还应该有一个稳定的舍入模式，使用舍入到舍入或舍入到偶数规则，该规则基于基数是能被4整除还是只能被2整除。

Programmer-controlled roundoff and the selection of a stable roundoff rule

The author suggests that every computer with floating-point addition and subtraction should have PSW control able roundoff facilities. Yohe's catalog should be included. There should also be a stable roundoff mode using the round-to-off or round-to-even rule based on whether the radix is divisible by four or only by two.
