Math.min() and Math.max() functions should apply ToNumber on each arguments always, even if a NaN argument occured previously and the result will be NaN. ECMA262 v5.1 15.8.2: "Each of the following Math object functions applies the ToNumber abstract operator to each of its arguments (in left-to-right order if there is more than one) and then performs a computation on the resulting Number value(s).
