什么格式的变量可以装下50亿的阶乘?
用数组的方法来存储。。源码
以下是源码本人对大数阶乘的研究：
一个学计算机的哥们问的问题，用数组求阶乘。源码autojs源码打包。源码。源码苹果应用页面源码即为了避免溢出、源码以及显示出阶乘的源码每一位结果。。源码
经过思考，源码我觉得用矩阵相乘的源码原理来作比较简单。。源码
下面是源码碧血银枪源码在 Matlab 中写的求阶乘的代码：
function JC(n)
A=1;
q=1;
for i=1:1:n
tmp=i;
p=0;
z=0;
while tmp>0
p=p+1;
B(p)=tmp-fix(tmp/)*;
tmp=fix(tmp/);
end
bb=zeros(1,p);
for ii=1:1:p
bb(p+1-ii)=B(ii);
end
for jj=1:1:p
B(jj)=bb(jj);
end
H=zeros(p,p+q-1);
for a=1:1:p
for b=1:1:q
H(a,a+b-1)=B(a).*A(b);
end
end
D=zeros(1,p+q-1);
for c=1:1:p+q-1
for d=1:1:p
D(c)=D(c)+H(d,c);
end
end
E(p+q-1)=D(p+q-1);
for w=p+q-2:-1:1
E(w)=D(w)+fix(E(w+1)/);
end
A(1)=E(1);
for x=2:1:p+q-1
A(x)=E(x)-fix(E(x)/)*;
end
r=length(A)-1;
while A(1)>0
z=z+1;
F(z)=A(1)-fix(A(1)/)*;
A(1)=fix(A(1)/);
end
G=zeros(1,z+r);
for y=z+1:1:z+r
G(y)=A(y-z+1);
end
for v=1:1:z
G(v)=F(z-v+1);
end
for s=1:1:z+r
A(s)=G(s);
end
q=z+r;
end
d=0;
for i=q:-1:1
if A(i)==0
d=d+1;
else
break;
end
end
A
q
d
最后的结果：
A：以数组的方式显示出阶乘的结果
q：阶乘结果的位数
d：阶乘结果的尾部连续出现的0的个数。

Delphi 中用动态数组不像 Matlab那么方便。。源码但是优化roc指标源码运算速度比 Matlab 快了很多，基本上是Matlab 运算速度的4倍左右，在我的机子上(Pentuim M 1.7GHz,MB内存)计算的阶乘时Dephi 用了不到秒，Matlab 用了大概2分钟。源码下载官网。
在百度中搜索：质数 用数组求阶乘
即可看到偶在“大富翁论坛”中发的帖子。。希望对你有帮助。。
