Float Question

[chiqui]

Hi, I have a problem
I must do several arithmetics operations with integer decimals numbers but I have the following prolem :

618 / 100.00 = 6.17999997

and I need 6.1800 as result.

I don't find the way to round the precision to 4 decimals .
Does anybody know how to do this?

Thanks in advance...

int main ( ) {
    float foo =  618 / 100.00;
    printf( "%.4f\n", foo );
    return 0;
}
