Number

Constructor

```new Number(`value`)
Number(`value`)```

With the `new` operator, the `Number( )` constructor converts its argument to a numeric value and returns a new Number object wrapped around that value. Without `new`, `Number( )` is a conversion function that converts its argument to a number and returns that value.

Constants

These constants are properties of `Number` itself, not of individual Number objects.

`Number.MAX_VALUE`

The largest representable number. Approximately 1.79E+308.

`Number.MIN_VALUE`

The smallest representable positive number. Approximately 5E-324.

`Number.NaN`

Not-a-number value. Same as the global `NaN`.

`Number.NEGATIVE_INFINITY`

Negative infinite value.

`Number.POSITIVE_INFINITY`

Infinite value. Same as global `Infinity`.

Methods

`toExponential(``digits``)`

Returns a string representation of the number, in exponential notation, with one digit before the decimal place and `digits` digits after the decimal place. The fractional part of the number is rounded, or padded with zeros so that it has the specified length. `digits` must be between 0 and 20, and if omitted, as many digits as necessary are used. JS 1.5; JScript 5.5; ECMA v3.

`toFixed(``digits``)`

Returns a string representation of the number that does not use exponential notation, and has exactly `digits` digits after the decimal place. `digits` must be between 0 and 20. The number is rounded or padded with zeros if necessary. JS 1.5; JScript 5.5; ECMA v3.

`toLocaleString( )`

Returns an implementation-dependent string representation of the number, formatted according ...
