number
The number perl script will print the English name of a number. One can print names of extremely large numbers (e.g. 1e1234567). Number can be run on the command line, or as a CGI script when run as 'number.cgi'. Number prints names in both the American and European naming system. It can also print the decimal expansion of a number in either naming system.

Recent releases
- 17 Sep 2006 17:03
Changes: This release improves the command line usage message. See "number -h" and the source code comments for details. In addition, the code works better with modern Apache Web servers when run in CGI mode (as number.cgi).
- 21 Feb 2005 08:40
Changes: The extra "t" was removed in numbers from one centillion (10^303) up until one quadringentillion (10^1201) as well as in all numbers that are a multiple of 1000 Latin powers beyond those values. Note that the on-line English Names of the Mersenne Primes (http://www.isthe.com/chongo/tech/math/prime/mersenne.html) have been corrected as well.
- 31 Dec 2003 16:24
Changes: A bug in line wrap / long line folding has been fixed, better use is made of Perl's Math::BigInt objects, and some minor code cleanup has been performed.
- 31 Dec 2002 23:35
Changes: A bug where the names of numbers greater than 10^(6*10^15) in European systems and greater than 10^(3*10^15) in the American system were incorrect was fixed. Some work-arounds for broken versions of the Math::BigInt module were implemented, and the Web size limit was increased.
- 14 Mar 2002 02:53
Changes: In this release, Number now sets the maximum post size. Uploads were disabled, there is improved error message formatting, and modifications to work with more recent CGI Perl modules.
