Java PWM getPosition() integer division bug?

    if (value < getMinNegativePwm()) {
        return 0.0;
    } else if (value > getMaxPositivePwm()) {
        return 1.0;
    } else {
        return (value - getMinNegativePwm()) / getFullRangeScaleFactor();
    }
}

Notice the final return statement. value, getMinNegativePwm(), and getFullRangeScaleFactor() are all of type int. Would this not cause the integer division to truncate to 0 for any result less than 1? I checked the C++ version of the same function, and sure enough, the numerator and denominator of the fraction are cast to float before the division.
