Format Doubles

[The Hobo]

I want to format a double variable to have two decimal places no matter what. Is there a way to do this without lengthy code?

Example:

4      -> 4.00
4.4   -> 4.40
4.44 -> 4.44
etc..

ostringstream oss;
oss.precision(2); // play with this :D
oss << num;

You can use any of the usual stream manipulators...

in standard C - printf("%8.2f",mydouble);

the 8 is the number of positions in front of the decimal point, the 2 is the number after it.

I know this was a few months ago, but thanks for the help.

I don't remember what I went with, but nowadays I use setprecision(2).

Man I really asked some noob questions back in the day.
