Displaying ".00"

acevans2 (27)
Hello guys. I just had a quick question.

I've got a program that is supposed to display information about net pay, social security withheld, etc. and thus needs to show dollar amounts like "1.00" instead of just "1"

How do I do that? I've got it all working otherwise. Everything is declared as floats and all that.

Thanks

}



I put it in where that example made it look like it should go, but it didn't work.

I still see whole numbers without following decimals like .00.

Do you see what I did wrong?

You also need to use the fixed flag.

cout << fixed << setprecision( 2 ) << 3.14159 << endl;
