     12  ...
     13  3. If count is undefined, let c be +∞.

     20  1. Let number be ? ToNumber(argument).
     21  2. If number is NaN, return +0.
     22  3. If number is +0, -0, +∞, or -∞, return number.
     23  4. Return the number value that is the same sign as number
     24      and whose magnitude is floor(abs(number)).
