摘要
R. Morris(参见IEEE译)。第一版。， vol.TC-20, p.1578-9, 1971)，建议在固定浮点系统中增加一个额外的字段，这样可以更有效地存储指数。指数存储在尽可能小的空间中，将额外的位传递给尾数。额外的字段用于监视指数的当前长度。精度和/或指数范围的增益超过了额外字段的开销和处理速度。作者提供了实现细节、误差分析和一些未来的研究思路。仿真结果供比较之用
R. Morris (see IEEE Trans. Comput., vol.TC-20, p.1578-9, 1971), suggested adding an extra field to the fixed floating point system, so that exponents can be stored more efficiently. The exponents are stored in the smallest possible space, passing the extra bits to the mantissa. The extra field is used to monitor the current length of the exponent. The gain in precision and/or exponent range outweighs the overhead of the extra field and the processing speed. The authors provide implementation details, error analysis, and some future research ideas. Simulation results are provided for comparison purposes.<>
