In arithmetic, a complex base system is a positional numeral system whose radix is an imaginary (proposed by Donald Knuth in 1955) or complex number (proposed by S. Khmelnik in 1964 and Walter F. Penney in 1965〔W. Penney, A "binary" system for complex numbers, JACM 12 (1965) 247-248.〕). ==In general== Let be an integral domain and the (Archimedean) absolute value on it. A number in a positional number system is represented as an expansion : , where : The cardinality is called the ''level of decomposition''. A positional number system or coding system is a pair : with radix and set of digits , and we write the standard set of digits with digits as :. Desirable are coding systems with the features * Every number in , e. g. the integers , the Gaussian integers or the integers 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Complex base systems」の詳細全文を読む
