Maybe a typo in the code

Is the 1e-20 in the second line a typo? In the old version this was 1e-10.
float utils_fast_atan2(float y, float x) {
    float abs_y = fabsf(y) + 1e-20; // kludge to prevent 0/0 condition
    float angle;

    if (x >= 0) {
        float r = (x - abs_y) / (x + abs_y);
        float rsq = r * r;
        angle = ((0.1963 * rsq) - 0.9817) * r + (M_PI / 4.0);
    } else {
        float r = (x + abs_y) / (abs_y - x);
        float rsq = r * r;
        angle = ((0.1963 * rsq) - 0.9817) * r + (3.0 * M_PI / 4.0);
    }

    if (y < 0) {
        return(-angle);
    } else {
        return(angle);
    }
}
