用vb编程n的阶乘加(n+1)的阶乘加(n+2)的阶乘加至(n+m)的阶乘 感谢感谢...
一个按钮。极限恐怕是：7.25741561530799e+306。不过显示成这样没有任何意义了。就前面几个数字是精确的，后面全部是0了。vb：120到130的阶乘：65169891884991400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000...

求vb,n个数连乘的流程图怎么写
Dim input As Integer = inputbox Dim n As Integer = 1 Dim j As Double = 1 If input = 0 Then input = 1 '因为0的阶乘等于1，这样处理后当你输入0时，运行结果就是1了 Do While n <= input j = j * n n = n + 1 Loop MsgBox("结果是" & j)...
如何用VB语言编程求数学阶乘?
1、首先定义一个函数，这个函数里的内容求n的阶乘，返回值是n的阶乘，如下图所示。2、函数定义完成之后，就要开始写main函数里的内容，还是定义变量。3、变量定义后就要赋值，把sum的值写为0.因为后面的求和就需要sum的初始值为0，如下图所示。4、下一步就是利用for循环了，for循环i初始值位1,结束...

vb阶乘代码 我哪里错了 (结果说我n1 = n1 * i这一步溢出)
代码没错，只是你的计算结果远远超过32位操作系统的承受能力了，从1连续乘到170就有300多位数了，到100000的话，估计如果把数字按米粒大小排起来的话能绕太阳好几圈了。而且如果用Double的话，只有前15位数是精确的，也就是说即使能计算到300位，后面的285位数也都是0，这有意义吗？
