The **Number** object represents numerical date, either integers or floating-point numbers. In general, you do not need to worry about **Number** objects because the browser automatically converts number literals to instances of the number class.

Creating a **number** object:

var val = new Number(number); |

If the argument cannot be converted into a number, it returns NaN (Not-a-Number).

Here is a list of each property and its description.

Property | Description |
---|---|

MAX_VALUE | The largest possible value a number in JavaScript can have 1.7976931348623157E+308 |

MIN_VALUE | The smallest possible value a number in JavaScript can have 5E-324 |

NaN | Equal to a value that is not a number. |

NEGATIVE_INFINITY | A value that is less than MIN_VALUE. |

POSITIVE_INFINITY | A value that is greater than MAX_VALUE |

prototype | A static property of the Number object. Use the prototype property to assign new properties and methods to the Number object in the current document |

The Number object contains only the default methods that are part of every object's definition.

Method | Description |
---|---|

constructor() | Returns the function that created this object's instance. By default this is the Number object. |

toExponential() | Forces a number to display in exponential notation, even if the number is in the range in which JavaScript normally uses standard notation. |

toFixed() | Formats a number with a specific number of digits to the right of the decimal. |

toLocaleString() | Returns a string value version of the current number in a format that may vary according to a browser's locale settings. |

toPrecision() | Defines how many total digits (including digits to the left and right of the decimal) to display of a number. |

toString() | Returns the string representation of the number's value. |

valueOf() | Returns the number's value. |
