计算机中r进制数的反码、原码和增码的表示与运算

REPRESENTATIONS AND ARITHMETICS OF (r- 1)'S COMPLEMENT, SIGN MAGNITUDE AND EXCESS CODE FOR NUMBERS WITH RADIX r

本文给出了r进制数的反码、原码和增码的定义,讨论了它们的性质和运算,分别导出了真数与反码、原码和增码之间关系的公式.

In this paper, definitions are first given to the (r-l)'s complement, sign magnitude and excess code of a number with radix r. Then their properties and arithmeti(?)s are discussed. Moreover, some formulas are presented for the relationship between a number and its (r-1)'s Complement, sign magnitude and excess code respectively.
