High-precision computing for ordinary numbers (non-floating points) for functional perfection, efficiency and compatibility

I thought it was a good code for myself, although I didn't encapsulate it as a class or put it in the header file.

I think it's just a structure, just fine.

Here's what to say.

First, the array version is obsolete because it does not support dynamic storage, there will be a lot of space left, a lot of unnecessary computation loss (although that's not a thing for the computer...). )

So I used the vector version.

The structure is named number, which means that it is actually a large number

Features currently supported

The ordinary four operations (although there are negative numbers, but not yet perfect!) ), directly with symbols instead of functions!

Order (.factor))

Power (.power()))

greatest common divisor (gcd() or .gcd())

Through Friends, you can even use cout and cin directly to input and output!

Example

Statement

number a,b;

number a(10),b(20);//Directly assign a to 10

input

cin>>a>>b;

a.input();b.input();//Of course, if you like, you can use this...

output

cout<<a<<b;

a.output();b.output();//Maybe no one likes it...

Assignment

a=10,b=20;

Add and subtract, multiply and subtract

number c=a+b;

c=a-b;

c=a*b;

c=a/b;

greatest common divisor

c=a.gcd(b);

c=gcd(a,b);

Factorial

c=a.factor();

Power

c=a.power(b);

c=power(a,b);
