0.999999 = 1

[AnotherMuggle]

I am reading the book C++ for Dummies to get a clearer picture on some of the more simple C++ concepts and I have come across a paragraph that I can't make sence of.

"C++ can correct for many forms of round-off error. For example, in output, C++ can determine that instead of 0.999999, that the user really meant 1...."

Can anyone demonstrate what this means in a small section of code?

Much appreciated
Tom

As a quick addition -> Is a double different from a float other than the storage capacity?

Thanks
