also avoids hitting the 255 string limit if you want to add 100's of values. eg.
>>> b05/max(0.001, [globals().update({"LOCALS":locals(), "ADD":float.__add__, "reduce":__import__("functools").reduce}), 0.0][1], max((, [LOCALS["b%.2d" % (i+1)] for i in range(5)])))
Since this more simple expression reaches the limit fairly quick...
>>> b05/max(0.001,b01+b02+b03+b04+b05)
