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.
Number.prototype.toExponential()Returns a string representing the number in exponential notation.
Number.prototype.toFixed()Returns a string representing the number in fixed-point notation.
Number.prototype.toLocaleString()Returns a string with a language sensitive representation of this number. Overrides the Object.prototype.toLocaleString() method.
Number.prototype.toPrecision()Returns a string representing the number to a specified precision in fixed-point or exponential notation.
Number.prototype.toString()Returns a string representing the specified object in the specified radix ("base"). Overrides the Object.prototype.toString() method.
Number.prototype.valueOf()Returns the primitive value of the specified object. Overrides the Object.prototype.valueOf() method.
