Trying to set Decimals in C++

[Sam-U-Rai]

I want to set the precision of the variable total_price to only 2 decimal places (EX: 2.82)

Here's the code:
#include
#include

//Price It
//3-13-07
double original_price (void);
double discount_price (void);
double calculate_price (double, double);

int main ()

{
double price;
double discount;
double total_price;
double tax;

for(int x=1; x<6; x++)
{
price = original_price();
discount = discount_price();

total_price = calculate_price(price,discount);

cout< cout< cout<
cout< cout<
cout<THIS IS WHERE I WANT THE 2 DECIMAL PLACES
cout<
}
return 0;

}


double original_price (void)
{
double price;

cout<<"What is the original price of the item?"< cin>>price;
cout< return price;
}


double discount_price (void)
{
double discount;

cout<<"What is the size of the discount? (in decimal value)"< cin>>discount;
cout< return discount;

}

double calculate_price (double price, double discount)

{
double total_price;
double tax;
tax = 0.06;
price = price - price * discount;
total_price = price * tax + price;


return total_price;

}

Before that line just put.

cout.precision( 2 );
cout.setf( ios::fixed );
cout.setf( ios::showpoint );

You also need to #include < iomanip > (sorry for the spaces, the forum makes it not be able to be seen without them)

You should just be able to put the "cout.precision (2);" but i've been taught toput the other stuff to. showpoint is used to show something like 22.00, where it will still display the ".00" and fixed just sets it to a fixed point notation.

Thanks for the advice. I know about the Manip. I actually have that included but this forum doesn't let me do stuff with < so alot of the code is missing.

Anyway, thanks. That worked. Thanks so much !

If you wrap your C++ code with PHP code tags it will display everything properly.

PHP Code:

#include <likethis.c>
