HDU-1042.N!(大数与小数相乘的乘法模拟)

本题大意:给定一个10000以内的整数n,让你求出n!并输出. 本题思路:先初始化一个存放答案的数组ans,初始ans[0] = 1,并初始化其剩下的元素为0,接着就从2开始依次与ans数组内的每一个数相乘,具体乘法过程见代码,需要注意的就是求divisor时自身此时的值也是需要加上的,还有就是注意当存在余数并且当前位数已经不够用的情况下才将总位数加一否则不加,答案里会出现很多前导零. #include <cstdio> #include <iostream> #include &…

javascript：解决两个小数相乘出现无限小数

两个小数相乘,会出现无限小数:先把小数乘以10或100或1000(小数点后有多少位就乘以多少),再相乘,最后再除以10或100或1000…
