Prototype extends native JavaScript numbers in order to provide:

- ObjectRange compatibility, through Number#succ.
- Ruby-like numerical loops with Number#times.
- Simple utility methods such as Number#toColorPart and Number#toPaddedString.

Here is the list of all the functions with examples dealing with Numbers.

**NOTE:** Make sure you have at least version 1.6 of prototype.js.

Methods | Description |
---|---|

abs() | Returns the absolute value of the number. |

ceil() | Returns the smallest integer greater than or equal to the number. |

floor() | Returns the largest integer less than or equal to the number. |

round() | Rounds the number to the nearest integer.. |

succ() | Returns the successor of the current Number, as defined by current + 1. Used to make numbers compatible with ObjectRange. |

times() | Encapsulates a regular [0..n[ loop, Ruby-style. |

toColorPart() | Produces a 2-digit hexadecimal representation of the number (which is therefore assumed to be in the [0..255] range). Useful for composing CSS color strings. |

toJSON() | Returns a JSON string. |

toPaddedString() | Converts the number into a string padded with 0s so that the string's length is at least equal to length. |
