样例
Uses Numberics;
var
a:BigInteger;
b:ansistring;
begin
readln(b); a:=b;
readln(b);
PrintfLn(a+b);
PrintfLn(a-b);
PrintfLn(a*b);
Printf(a div b)
end.上述样例可以读入2行大数a,b 分别输出4行a+b,a-b,a*b,a div b.

●大数和许多类型可以直接隐式转换或者用BigInteger()强制转换
■大数并无压位，常数大
■大数间不能直接赋值
■大数除法的时间复杂度是O(n^2)，大数乘法的时间复杂度是O(nlogn)，大数加法的时间复杂度是O(n)
