This is a measure of information content; it is **fundamentally** impossible to store more than this number of yes/no decisions in it. With three-way decisions the arithmetic becomes slightly more involved because they represent fractional numbers of bits (... | You can store the value as a number if you have a datatype that can represent more than `choices``count` possible values.
