Doubles doing my head in!

Hello everybody.

When I write the code...

cout << 83865.5657 / 0.01;

...it outputs 8.38656e+006 yet when I do it with Windows Calculator I get 8386556.57. Why is this? I'm not very good at maths and don't really understand what the e+006 on the end of my result means. Also not being very good at maths I can't work out why I get different results. Also is it possible to out put the result without the e+006 notation on the end?

Thanks for you help
Andrew

That's exponential notation.
The +6 means: to view it in normal form, move the decimal point right 6 digits.
