Thread: Rounding help

Hey can someone help explain how to use the rounding function.

I want to round to the 2nd digit in a float. Such as 1.85458 to 1.85. How would i go about doing this. I currently keep rounding to the closest integer so the above would round to 2. Thank you in advance for your help!

Code:

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


int main(void)
{
    float n;
    do
    {
    printf("input a floated number to 7th decimal: ");
    n = ask for integer;
    }
    while (n != 0);
    
    n = roundf(n);
    
    printf("%.7f\n", n);
}
