I wrote a small program that reads two integers using scanf
and then performs various arithmetic calculations. I'm using printf
to display the results. How can I make printf
display only two digits after the decimal point? Starting with the simplified code sample:
#include <stdio.h>
int main(void)
{
double third = 1.0 / 3.0;
// display data
printf("\n%20s%20s", "Description", "Data");
printf("\n%20s%20s", "-----------", "----");
printf("\n%20s%20lf", "One third", third);
printf("\n");
return 0;
}
This prints "0.333333" for the value of third
. How would I alter the above to get the following output?
\n Description Data\n ----------- ---- \n One third 0.33\n
use "%.2f" at the place you want.
For example, modify the following statement
printf("\n%20s%20lf", "Fraction", quotientdecimal);
into this one :
printf("\n%20s%.2f", "Fraction", quotientdecimal);
will only display two fraction numbers of the variable quotlentdecimal.
