To display numbers you should use NumberFormat or NumberFormat2.

To do calculations that require decimal precision you should not use floating point calculations. agrahm's BigNumbers library is the answer to this problem. It's not a display issue it's calculation issue.

In most cases BigNumber calculations are not necessaray, Double calculations are enough.
But the display is anoying, therefore the suggestion to use NumberFormat.
