Is there a stream class member equivalent to sprintf()

[Tight_Coder_Ex]

I'd like to read a floating point value cin >> Value where Value is declared as a double and then output it to a string justified to two decimal places. I understand how to do it using a temporary file, but I'd like to avoid that method and sprintf() if possible

sorry but cant you use setwidth function ? Or something similar?

That accomplishes the formatting I want, but still doesn't solve the problem of assigning it to a string variable.

Not sure if I know what I'm talking about here, but couldnt you put your double / float into an array then convert the array to a string?
