smaller numbers than a given r

The code is working just when r is smaller than 1 (ex: 0.99), but if r = 1 nothing appears:

#include <stdio.h>
#include <stdlib.h>

int main() {
    int nr = 2;
    float x1 = 0, x2 = 0, nextTerm = 0, r;

    scanf("%f", &r);

    while (nextTerm < r) {
        nextTerm = (1 + x2 + x1 * x1) / 3;
        x1 = x2;
        x2 = nextTerm;
        nr++;
    }
    printf("%d", nr);

    return 0;
}

When you set a number greater than or equals to 1 while you are looping validated by a division of numbers smaller than 1, you are basically dividing a number smaller than 1 by a greater one (3, in the (1 + x2 + x1 * x1) / 3;), so you'll never get a number greater than 1 to stop the loop. Because no matter what you put in the prompt, if the values of x1 and x2 are smaller than 3 you'll never get a number greater than 1.
