JavaScript Number Object
---------Number object is the wrapper object for the original numeric value.
Create a Number Object
var num = new number (10);
var num = number (10); ---parentheses are the values of the number object that you want to create or the value that is converted to numbers.
return value:
1. Returns a newly created number object when number () and operator new are used together as constructors
2, directly using number () as a function to call, it will convert its own parameters to the numeric value of an element, and return it (if the conversion fails, then return nan)

/* Below a simple example * *
Number (NULL)//0
Number (true)//1
Number (false)//0
Number (' 1 ')//1
Number (' a ')//nan
Number (undefined)//nan
