decimal places - Tilted Forum Project Discussion Community

I created a program that converts centigrade to farehenheit, and I want to only print the answer to two decimal places. I can probably leave it as it is, since the problem doesn't ask to be formatted that way, but if get a problem that involves money, I would like to know how to do it.

Here's the problem, and the language is c:

Code:

/* This program converts Centigrade to Farenheit.
Written by: zero2
*/

#include <stdio.h>

int main (void)
{
/*Local Definitions*/
float cent;
float far;


/*Statements*/
printf("Enter Temperature in Centigrade\n");
scanf(" %f", &cent);
far = 32 + (cent * 1.8);
printf("Temperature in Centigrade: %f\nTempreture in Farenheitt: %f\n", cent, far);
	return 0;
}
/* main */

/* Results 

Enter Temperature in Centigrade
37
Temperature in Centigrade: 37.000000
Tempreture in Farenheitt: 98.599998
Press any key to continue */

Read the documentation for printf, it will do exactly what you want.

Thanks a-j, I just had to put the formating in the printf statement like such:

Code:

printf("Temperature in Centigrade: %3.2f\nTempreture in Farenheitt: %3.2f\n", cent, far);

I probably should of mentioned that I was using visual studio, and am just a beginner at this.

I kind of knew that it had something to do with the printf statement, but I kept putting it in the wrong place, before % sign, which gave me some strange answers.
