I love assignment operators (+=, *=, etc.) especially as variable names get longer.  But the one thing I'm having problems with is rounding.  I haven't found a way around the issue.  The following two statements are equivalent:

  Quantity = Quantity * perUnit;
  Quantity *= perUnit;

Yay!  But how do I do this:

  eval(h) Quantity = Quantity * perUnit;

I don't see any way to change that particular line to use the assignment operator.  Has anybody run into this, and is there a workaround?
