rs.ac.ns.ftn.tmd.fuzzy.exceptions.FuzzyMultiplicationByZeroException
A Runtime exception thrown when user tries to multiply numbers which contain zero in their support sets. It causes numbers to diverge and operation results in an invalid fuzzy number. @author Nikola Kolarovic

    // first, if one contains zero in confidence interval, LR-fuzzy numbers don't support that!
    if (((LRFuzzyNumber)this).isPositive()==0 || ((LRFuzzyNumber)arg2).isPositive()==0 ) {
      throw new FuzzyMultiplicationByZeroException();
