I assumed integer-only input and casting. Here is a fixed (tested) version: <?php function RomanDigit($dig, $one, $five, $ten) { switch($dig) { case 0: return ""; case 1: return "$one"; case 2: return "$one$one"; case 3: return "$one$one$one"; case 4: return "$one$five"; case 5: return "$five"; case 6: return "$five$one"; case 7: return "$five$one$one"; case 8: return "$five$one$one$one"; case 9: return "$one$ten"; } } function IntToRoman($num) { $num = (int) $num; if (($num < 1) || ($num > 3999)) return("No corresponding Roman number!"); $m = (int) ($num * 0.001); $num -= $m*1000; $c = (int) ($num * 0.01); $num -= $c*100; $x = (int) ($num * 0.1); $num -= $x*10; $i = (int) ($num); // echo "m = $m, c = $c, x = $x, i = $i "; return( RomanDigit($m, 'M', '', '') . RomanDigit($c, 'C', 'D', 'M') . RomanDigit($x, 'X', 'L', 'C') . RomanDigit($i, 'I', 'V', 'X') ); } ?> and my test script: <?php include("to_roman.php"); $test = array( 8, 19, 155, 980, 9.8, -3, 3999, 4000, "abc", "", array() ); foreach($test as $num) echo "$num => ".IntToRoman($num)."<br/>"; ?> -- Hugh Bothwell hugh_bothwell@hotmail.com Kingston ON Canada v3.1 GCS/E/AT d- s+: a- C+++ L++>+++$ P+ E- W+++$ N++ K? w++ M PS+ PE++ Y+ PGP+ t-- 5++ !X R+ tv b++++ DI+++ D-(++) G+ e(++) h-- r- y+ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
