Title Page Software Version Description for Data::Str2Num - convert a scalar string to an integer Revision: A Version: 0.02 Date: 2003/07/21 Prepared for: General Public Prepared by: SoftwareDiamonds.com Esupport@SoftwareDiamonds.comE Copyright: copyright © 2003 Software Diamonds Classification: NONE 1.0 SCOPE This paragraph identifies and provides an overview of the released files. 1.1 Identification This release, identified in 3.2, is a collection of Perl modules that extend the capabilities of the Perl language. 1.2 System overview The "Data::Str2Num" module extends the Perl language (the system). The "Data::Str2int" module translates an scalar string to a scalar integer. Perl itself has a documented function, '0+$x', that converts a scalar to so that its internal storage is an integer (See p.351, 3rd Edition of Programming Perl). If it cannot perform the conversion, it leaves the integer 0. Surprising not all Perls, some Microsoft Perls in particular, may leave the internal storage as a scalar string. The "str2int" function is basically the same except if it cannot perform the conversion to an integer, it returns an "undef" instead of a 0. Also, if the string is a decimal or floating point, it will return an undef. This makes it not only useful for forcing an integer conversion but also for testing a scalar to see if it is in fact an integer scalar. 1.3 Document overview.

The distribution file is at the following respositories: http://www.softwarediamonds/packages/Data-Str2Num-0.02 http://www.perl.com/CPAN-local/authors/id/S/SO/SOFTDIA/Data-Str2Num-0.02 Prerequistes. 'File::TestPath' => '1.1', 'File::SmartNL' => '1.1', 'File::Package' => '1.1', 'Test::Tech' => '1.08', Security, privacy, or safety precautions. None. Installation Tests. Most Perl installation software will run the following test script(s) as part of the installation: t/Data/Str2Num.t Installation support. If there are installation problems or questions with the installation contact 603 882-0846 Esupport@SoftwareDiamonds.comE 3.7 Possible problems and known errors There is still much work needed to ensure the quality of this module as follows: * State the functional requirements for each method including not only the GO paths but also what to expect for the NOGO paths * All the tests are GO path tests. Should add NOGO tests. * Add the requirements addressed as *# R: * comment to the tests * Write a program to build a matrix to trace test step to the requirements and vice versa by parsing the *# R: * comments. Automatically insert the matrix in the Test::TestUtil POD. 4.0 NOTES The following are useful acronyms: .d extension for a Perl demo script file .pm extension for a Perl Library Module .t extension for a Perl test script file 2.0 SEE ALSO Data::Str2Num
