或者你先自己算一遍。。给写在哪个文件里，然后再算的时候直接读取就行了，半秒都用不了……

你做梦呢，10000的阶乘就够你算N辈子了，还100000，你不如
算100000的100000次方，全是0的话你还有可能数的过来，可能性为0~~~

For numIndex As Integer = 2 To number
carry = 0
For arrayIndex = 0 To arrayTail
midProct = proct(arrayIndex) * numIndex + carry
carry = midProct \ DIVISOR
proct(arrayIndex) = midProct - DIVISOR * carry
Next arrayIndex

Do While carry <> 0
proct(arrayIndex) = carry Mod DIVISOR
carry = carry \ DIVISOR
arrayIndex += 1
Loop
arrayTail = arrayIndex - 1
Next numIndex
