For example, int
main (void)
{
mpz_class a, b, c;
a = 1234;
b = "-5678";
c = a+b;
cout << "sum is " << c << "\n";
cout << "absolute value is " << abs(c) << "\n";
return 0;
} An important feature of the implementation is that an expression like a=b+c results in a single call to the corresponding mpz_add ,
without using a temporary for the b+c part. Expressions which by their
nature imply intermediate values, like a=b*c+d*e , still use temporaries
though. The classes can be...
