Formatting numbers

I have an number (double). I want to print this number in with two decimals. Example:

double i = 2;
//This should be printed as 2.00

double j = 2.5
//This should be printed as 2.50

double j = 2.567
//This should be printed as 2.57

Another nice QString method for string formatting ist sprintf.
For example

Source code

int i = 5;
int count = 6;
QString progress;
progress.sprintf("%d of %d files", i, count);
