C float rounding up

In C, you can round a float up using the ceil() function from the math.h library. Here's an example:

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

int main() {
    float num = 3.14;
    float roundedUp = ceil(num);
    printf("Rounded up value: %.2f\n", roundedUp);
    return 0;
}

This code will output 4.00, which is the rounded up value of 3.14.
