How do i make a floating point number display up to 2 decimal places?
for instance, a program displaying CalBurnedPerStep as a floating point number:
1 calorie should be displayed as 1.00 calorie
and a number like 1.2 should be 1.20
and a number 1.25 will remain same.
here's a snippet of the code:
%26lt;%26lt; setprecision(2) %26lt;%26lt; caloriesBurnedPerStep %26lt;%26lt;
what do i need to insert other than setprecision(n)? It simply doesn't show up the extra 0's that i need it to display.
thanks in advance!
C++ help!!!?
That's easy. You also need to use the 'fixed' notation, as follows:
cout %26lt;%26lt; fixed %26lt;%26lt; setprecision(2) %26lt;%26lt; caloriesBurnedPerStep;
Reply:im sorry...wat?
Reply:if u r using a 'c' programming language den u can simply write "0.2%f" but since u r using c++ it doesnot hold any method directly but u can print it separatedly n den mix.........
like
%26lt;%26lt;22%26lt;%26lt;".00"
hope so u hv understand...............
Reply:im giving you the program? see huv it works
It's Turbo c++
# include%26lt;iostream.h%26gt;
# include%26lt;conio.h%26gt;
# include%26lt;iomanip.h%26gt;
void main()
{
float cal=1.2366475;
cout.setf(floatfield,fixedpoint);
cout.setprecision(2);
cout%26lt;%26lt;cal;
}
Ans:
1.24
Reply:Trying setting CalBurnedPerStep to 0.00 when declaring it.
CalBurnedPerStep = 0.00
Reply:ok whoever that can answer that is SMART!

The correct way is to use fixed with setprecision(2). Don't forget the iomanip header file too of course.
