How Can I Round Type Float Variable WHEN PRINTED In C Language?

Question

Is there a function to round a float in C or do I need to write my own?

Before I cause any confusion...this is what I am using in C++

cout.setf(ios::fixed);
..
cout.precision(3);
..

I used that to round all PRINTED numbers to 3 decimal places in C++. I can't get that to work in C. Any help?

Try this:

printf("%.3f", float_value);

where .3f indicates that you want precision 3.

You're doing it wrong. Your code example implies `sprintf` not `printf`. – jer Sep 01 '11 at 20:33

Do this:

printf("%0.3f", myFloat);

You can achieve that with printf:

printf("%0.3f", n);
