Multiplies the value of this fraction by another, returning the result in reduced form.

Usage

From source file:org.libreplan.web.resourceload.LoadPeriodGenerator.java

private int calculateLoadPercentage(EffortDuration totalEffort, EffortDuration effortAssigned) {
    if (totalEffort.isZero()) {
        return effortAssigned.isZero() ? 0 : Integer.MAX_VALUE;
    }/* w w w  . j  av a 2 s .c om*/

    if (effortAssigned.isZero()) {
        LOG.warn("total effort is " + totalEffort + " but effortAssigned is zero");
        getEffortAssigned();

        return 0;
    }
    Fraction fraction = effortAssigned.divivedBy(totalEffort);
    Fraction percentage = fraction.multiplyBy(Fraction.getFraction(100, 1));

    return percentage.intValue();
}
