Thread: How do I print out only the decimal places for a number in C?

Code:

printf("The decimal places you entered are %f .\n", n1-floor(n1));

%f may need to be %.4f

I've tried that and it still prints out the whole number in front of the decimal places. Is there anyway to - the portion of the whole number so I am just left with the decimals?

convert to int and subtract the int value from the float

How would I do that?

I am obligated to type something here so the post goes through.

Thanks a bunch.

Code:

#include <stdio.h>
#include <math.h>


int main()
{
    float n1;
    
    printf("Please enter a number with at least 4 decimal places:\n");
    scanf("%f", &n1);
    printf("The decimal places you entered are %f .\n", n1-floor(n1));


    return 0;
}

works perfectly!
