The JavaScript Number type is a double-precision 64-bit binary format IEEE 754 value, like double in Java or C#. This means it can represent fractional values, but there are some limits to the stored number's magnitude a

Many built-in operations that expect numbers first coerce their arguments to numbers (which is largely why Number objects behave similarly to number primitives). The operation can be summarized as follows:
The smallest interval between two representable numbers.
The smallest interval between two representable numbers.
Determine whether the passed value is a finite number.
Determine whether the passed value is a finite number.
The constructor function that created the instance object. For Number instances, the initial value is the Number constructor.
Number.prototype.toExponential()
Returns a string representing the number in exponential notation.
Returns a string representing the number in exponential notation.
Number.prototype.toLocaleString()
Returns a string representing the number in exponential notation.
Object.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 in exponential notation.
