How to Use the Number Object
This article describes Number, a primitive wrapper object used to represent and manipulate numbers. "Number" represents floating point numbers like 45 or -3.24. Numbers are encoded as 64-bit binary, much like double in Java. There are some helpful functions in "Number" like Number ("123") would return the actual number 123. However, a "Number" ("Iamnotanumber") would return NaN (Not-a-Number) because it could not convert that into a number.
