The problem is that when I derive a new class from float, the darn thing won't let me create a constructor that accepts more than one argument. I need two arguments: one for the numerical value and one for the units. But when I try to give the constructor two arguments, I get this when I call the constructor:
TypeError: float() takes at most 1 argument (2 given) In other words, python doesn't seem to want to let me "extend" the float type. I don't understand the reason for that, but I assume there is a reason. -- http://mail.python.org/mailman/listinfo/python-list
