a php version. (yeah, i know php is considered a dirty word around here ;-) )
* ducks * transcribed from ruby version: #! /usr/bin/php <?php $amount = (float) $argv[1]; $remainder = $amount % 5; $base_amount = $amount - $remainder; if ($remainder > 2) $x = 5; else $x = 0; print $base_amount + $x . "\n"; ?> 1. php, $argv is an array of command line args, starting at $argv[1] (same reason as with python and C). 2. strings don't have methods :-) 3. could use php built in function floatval() instead of casting with (float): $amount = floatval($argv[1]); question: why use float and not int? the ruby, python, and php examples don't work as expected if the number supplied to the script is a simple float.

"\n"; ?> [EMAIL PROTECTED]:~/$ ./round5short.php 7.4 5 cheers justin _______________________________________________ coders mailing list coders@slug.org.au http://lists.slug.org.au/listinfo/coders
