There is a misleading sentence: “The maximum numerical value that may be stored is 2^53, or 9,007,199,254,740,992, and the minimum is -9,007,199,254,740,992.” This implies that the object can only hold values in a smaller range than IntValues, which is not actually the case (and may lead to people wondering how to store values above the limit for IntValues). The page should instead list that the maximum value that can be stored is 1.79769e+308 (the actual limit) and maybe note that the 2^53 limit is for exact representation of all integers.
