    Did you notice that the numbers you wrote were different?  I'll assume that you meant the larger,
first one.

That number will fit into a double.  But, a 'long long' is probably what you want.  Here is a program
that shows that the number will fit into a double.

#include <iostream.h>

int main()
{
 int Int = 25834242042;
 float Float = 25834242042;
 double Double = 25834242042;
 long long Long = 25834242042;
 cout.precision(15);
 cout << Int << endl
      << Float << endl
      << Double << endl
      << Long << endl;
 }

===Output===
64438266
25834242048
25834242042
25834242042
