高精度模板

我其實只是存個模板……

真的只是存個模板……

而已啦……

支援高精度加減乘除以及快速冪……但是沒有負數……（少用而且不想寫……要的話自己寫寫符號位……）

#include#include

#include
using
namespace
std;
const
int bi=1e4,mn=300
;char c[1001
];struct
big    inline

operator =(int
x)        a[

這是乙個int128模版，用兩個unsigned long long儲存

#define ll unsigned long longll m[

2315
];struct
mmh    
void
half()
void
two()
};mmh 
operator +(const mmh &x,const mmh &y)
mmh 
operator +(const mmh &x,const
int &y)
mmh 
operator -(const mmh &x,const mmh &y)
mmh 
operator -(const mmh &x,const
int &y)
bool
operator
bool
operator >(const mmh &x,const mmh &y)
bool
operator !=(const mmh &x,const mmh &y)
bool
operator ==(const mmh &x,const mmh &y)
mmh 
operator *(const mmh &x,const mmh &y)
sss+=clock();
return
mmh;
}ll s=(1ull<<32)-1
;    ll a=(x.b>>32)*(y.b>>32),_b1=(x.b&s)*(y.b>>32),b=_b1+(x.b>>32)*(y.b&s),c=(x.b&s)*(y.b&s),d;
