Abstract

The Slide number format divides the real number line into connected sets. Compared to the unum format [3], there is no ubit, no infinity, and values are placed on a logarithmic scale with base 10. Formal definitions for Slides and intervals composed of Slide pairs are provided. The relative error is compared with that of single precision floats. The performance of conversions to and from human readable form is measured.

幻灯片编号格式
幻灯片数字格式将实数线划分为连通的集合。与unum格式[3]相比,unum没有ubit,也没有无穷大,数值是以10为基数的对数刻度。给出了幻灯片和由幻灯片对组成的区间的正式定义。并与单精度浮点数的相对误差进行了比较。测量了从人类可读形式转换到人类可读形式的性能。
