大数除法的实现算法，不仅能实现两个大数的除法，而且能实现浮点数之间以及浮点数与整数之间的除法-majority of the division algorithm, is not only able to make large numbers of division two, but to achieve a float and between integer and floating point divider between the

写一个函数，输入参数有四个，分别是map<string,float>型数据，整数，float型数组,string型数组。返回结果，将map中的数据按float值进行排序，并将排序后的结果保存到float、string两个数组中，两个数组元素必须对应于map数据。-Write a function, there are four input parameters, are the map <string,float> data, integer, float array,
