See Also Methods Properties

An object representation of the number data type and placeholder for numeric constants.
new Number( value )

The value argument is the sought numerical value for the object.

JScript creates Number objects as required from numerical values. It is rarely necessary to create Number objects explicitly.

The primary purposes for the Number object are to collect its properties into one object, and to allow numbers to be converted into strings via the toString method.
