Display a number decimal format instead as an exponential in cout

Question

I calculated a total of floats and I got a number like 509990e-405. I\'m assuming this is the short version; how can I cout this as a full number?

Answer 1

You can write your own BigNumber class that stores the results as strings. You would have to implement all of your numeric operations and I'm guessing performance will be an issue. But it can be done, no problem -- assuming that is what you want.
