Description: 使用数组精确计算M/N(0<M<N<=100)的值。如果M/N是无限循环小数，则计算并输出它的第一循环节，同时要求输出 循环节的起止位置(小数位的序号)
*问题分析与算法设计
由于计算机字长的限制，常规的浮点运算都有精度限制，为了得到高精度的计算结果，就必须自行设计实现方法。
为了实现高精度的计算，可将商存放在一维数组中，数组的每个元素存放一位十进制数，即商的第一位存放在第一个元素中，商的第二位存放在第二个元素中....，依次类推。这样就可以使用数组不表示一个高精度的计算结果。
进行除法运算时可以模拟人的手工操作，即每次求出商的第一位后，将余数乘以10，再计算商的下一位，重复以上过程，当某次计算后的余数为0 时，表示M/N为有限不循环小数某次计算后的余数与前面的某个余数相同时，则M/N为无限循环小数，从该余数第一次出现之后所求得的各位数就是小数的循环节。
程序具体实现时，采用了数组和其它一些技巧来保存除法运算所得到的余数和商的各位数。

Description: 计算机里整数和小数形式就是按普通格式进行存储，例如1024、3.1415926等等，这个没什么特点，但是这样的数精度不高，表达也不够全面，为了能够有一种数的通用表示法，就发明了浮点数。
浮点数的表示形式有点像科学计数法（*.*****×10^***），它的表示形式是0.*****×10^***，在计算机中的形式为 .***** e ±***），其中前面的星号代表定点小数，也就是整数部分为0的纯小数，后面的指数部分是定点整数。利用这样的形式就能表示出任意一个整数和小数，例如1024就能表示成0.1024×10^4，也就是 .1024e+004，3.1415926就能表示成0.31415926×10^1，也就是 .31415926e+001，这就是浮点数。浮点数进行的运算就是浮点运算。
浮点运算比常规运算更复杂，因此计算机进行浮点运算速度要比进行常规运算慢得多。(Floating point representation is a bit like scientific notation (*.***** * 10^***), its representation is 0.***** * 10^*** in the computer in the form of.***** e +, * * *) in front of the asterisk represents fixed-point decimal, which is part of the 0 pure decimal integer index, part of the back is a fixed integer. In this way, any integer and decimal can be expressed. For example, 1024 can be expressed as 0.1024 * 10^4, that is,.1024e+004, 3.1415926 can be expressed as 0.31415926 * 10^1, that is.31415926e+001, that is the floating point number. The operation of floating-point numbers is floating point operation.)
