Displaying fractions simple problem

**newby01** · 01-19-2008

i'm just starting to learn C and i have a problem with displaying fractions.

My code:

insert

Code:

#include<stdio.h>
main()
{     
      float num = 2/3;
      printf("%f", num);
      getchar();
      return 0;
      }

When i run this, the ouput is:

0.000000

How do i get it to output .666666??
Also, how would i get the output to display correct to 6 decimal places?
Thanx

How do i get it to output .666666??

By using floating point division instead of integer division.

Also, how would i get the output to display correct to 6 decimal places?

By using the format flags for printf(). For example:

Code:

#include<stdio.h>

int main(void)
{
    float num = 2.0f / 3.0f;
    printf("&#37;.6f", num);
    getchar();
    return 0;
}
