Thread: exponential form etc

Hi

No matter what value of "a" I use the "b" is stuck at 2,60,000 (1+2.6e5). Why is so?

How could I also get the value of "b" in exponential form?

Is the the "F" I used in the declaration "float a = 2.6e5F" really important? As far as my limited knowledge goes "F" could be omitted. But there should be some reason to include this. I have seen a author using it in the book.

It would be extremely kind of you if you could help me with the above queries. Thanks a lot for your time.

Code:

#include <iostream>

using namespace std;

int main()

{
 	
 	float a = 2.6e5F;
 	float b = 1 + a;
 	
 	cout << "enter a = ";
 	cin >> a;
 	
 	cout << b << endl;
 	
 	system("pause");
 	
}
