## Number

The `Number` Javacript object represents any kind of number. JavaScript doesn't distinguish separate types of numbers, such as integers or floats. They are all stored in a unified, 64-bit Floating Point format, accorfing to the international IEEE 754 standard<sup>1</sup>.

New `Number` objects are created like this: `var num = new Number(value)` although most commonly they can be created simply by assigning a numeric value to a variable: `var num = 1.616;`. In a non-constructor context (i.e., without the `new` operator), `Number` can be used to perform a type conversion. If the argument cannot be converted into a number, it returns [`NaN`](https://guide.freecodecamp.org/javascript/standard-objects/number/number-nan).
