Javascript numbers reference.

Javascript build-in Number object reference.

Syntax:	toExponential(fractionDigits)
	The method will return the number in an exponential form with a digit before the comma and "fractionDigits" digits after the comma. The fractional part of the number is rounded upward.
Return value:	A string.
fractionDigits:	The number of digits (0 - 20) that you want after the decimal point. If the argument is omitted, then a number of decimal places as necessary will be used.
An example of using the toExponential() :

Syntax:	Number.prototype.constructor
	This property of the Number.prototype holds the reference back to the Number object. You can find all the Number constants through this constructor. (Number.prototype.constructor.MAX_VALUE is the same as Number.MAX_VALUE)
Important note:	This is the same as the constructor property of an instantiated object

Syntax:	Number.constructor
	The constructor property is a reference to the function that will be invoked to create a Number object.

Number.MAX_VALUE:	Largest representable number. (1.7976931348623157e+308)
Number.MIN_VALUE:	Smallest (closest to zero) representable number. (5e-324)
Number.NaN:	Special Not-a-Number value. (NaN)
Number.POSITIVE_INFINITY:	Special value to represent infinity. (Infinity)
Number.NEGATIVE_INFINITY:	Special value to represent negative infinity. (-Infinity)

Syntax:	toFixed(digits)
	The method will return the number with "digits" digits after the comma. The fractional part of the number is rounded upward.
Return value:	A string.
digits:	The number of digits (0 - 20) you will have after the decimal point. If no argument is given, there will be no digits after the decimal point.
An example of using the toFixed() :

Syntax:	toPrecision(precision)
	The method will return as fixed-point number with "precision" digits if the precision is large enough for the integer part of the number. If not an exponential notation will be used with one digit before the decimal place and precision-1 digits after the decimal place. The fractional part of the number is rounded upward and padding with zeroes is done if required.
Return value:	A string.
precision:	The number of digits (1 - 21) that you want to appear in the returned string. If the argument is omitted, the toString() method is used instead.
An example of using the toPrecision() :

Syntax:	toString(radix)
	The method will return a string representation of the number, in the specified base given with the optional "radix" parameter.
Return value:	A string.
radix:	This is optional and specifies base (2 -36). If this is omitted, base 10 is used.
An example of using the toString() :

Syntax:	toLocaleString( )
	The method will return a string representation of the number formatted according to local conventions. This will may affect such things as the punctuation and characters used for the decimal point and/or the thousands separator.
Return value:	A string.

Syntax:	valueOf()
	This method returns the primitive value of the number Nummber object. To call this method explicitly is rarely necessary since JavaScript uses the method implicitly if necessary.
Return value:	The primitive number of the object.

Syntax:	Number.prototype
	The prototype property is a reference to an object that contains all build-in methods that can be used by alle instances of Number-objects or primitive numbers. You can apply your own methods to the Number object through this prototype property.
Important note:	Is not directly available on an instantiated object.
An example of using the prototype :
