Exponent Output

[amagr]

Hey!
I want to know how to output numbers in exponent. with cout<<scientifix<<100.0; it works. But if i:

 int x=100;
cout<<scientific<<x;

It doesnt. Thanks for your help.

The x is int. The 100.0 is double. You can static_cast.

std::scientific only has an effect on floating-point numbers (float or double).

What you could do is to change x to double

double x = 100;
cout << scientific << x;

or cast x to a double before printing it.

int x = 100;
cout << scientific << static_cast<double>(x);

Thank both of you.
