本文所要解决的的问题是十进制的转换。即将十进制转换为任意的r(r是大于一的正整数)进制问题。因为要解决一个问题必须要对其进行解剖，所以首先对问题进行详细的描述对题目有充分的了解，其次是对问题的详细分析，主要包括对问题的解的分析以及对问题的解的结论的分析。第三主要是建立问题的解决方案，虽然解决问题的方法有很多种，本文主要采用即：把一个十进制数转换成非十进制数（基数记作R）分成两步.整数部分转换时采用“除R取余法”；-In this paper, which we have to resolve the problem is that the metric system conversion. Converted to the metric system is about to arbitrary r (r is a positive integer greater than 1) M-ary problem. Because the need to solve a problem must be dissected, so first detailed descr iption of the issue to have a full understanding of the subject, followed by a detailed analysis of issues, including the solution of the problem analysis and solution of the problem of the conclusions analysis. The third major problem is to establish a solution, although the solution to the problem There are many ways, this article mainly uses namely: a decimal number to convert non-decimal number (base recorded as R) is divided into two steps. Integral part of the conversion used
