Thread: Decimal points

I'm fairly new to C, and I have an assignment, this is what I came up with so far:

Code:

 #include<stdio.h>int main()
{
float b,e;
printf("Enter beginning odometer reading=>");
scanf("%f",&b);
printf("\nEnter ending odometer reading=>");
scanf("%f",&e);
printf("\nYou traveled %.2f miles. At $0.35 per mile, your reimbursement is %.3f.",(e-b),(e-b)*0.35);
return 0;
}

My question is, how can I get rid of the extra decimal point, when I input the following:
13505.2 (for the beginning odometer reading)
13810.65 (for the ending odometer reading)

It gives me values of 305.40 and 106.890, how do I get rid of the extra zeroes?

Are you sure it gives you 305.40 and not 305.45?

At any rate, you told it to print two and three decimal places, respectively, so why are you complaining when it does?

If you used %f only in the printf() statement format, I wonder if the last zero would be truncated off the printed number?

You're thinking of %g, I think.

shoot, I made several mistakes, the value for the ending odometer was suppose to be 13810.6. Anyways... thanks for pointing that out, I didn't realise that I stated that. I replaced the values and it works fine.
