The numeric value of the Number object being created. This argument will be converted to a number, if necessary.
The newly constructed Number object
Convert a number to a string, using a specified radix (base).
Return the primitive numeric value contained by the Number object.
The Number() constructor is actually more commonly used as a place-holder for five useful numeric constants: the largest and smallest representable numbers, positive and negative infinity, and the special Not-a-Number value. Note that these values are properties of the Number() constructor function itself, not of individual number objects. For example, you use the MAX_VALUE property as follows:
biggest = Number.MAX_VALUE
n = new Number(2); biggest = n.MAX_VALUE
value = 1234; binary_value = n.toString(2);
