#26713 [NEW]: Detail

From: turgut85 at hotmail dot com Operating system: Windows XP PHP version: Irrelevant PHP Bug Type: Math related Bug description: Detail Description: ------------ Is anyone can help me about the code below . Here is I am collecting values according to increment value between number ranges. My first example never hits the end point although the end is in range but second hits the range or third. Why php treats numbers differently or cannot understand the last value is still below end point. Can anyone tell me. Reproduce code: --------------- <?PHP function increment ($start, $end, $increment_val) { $ret_arry = array (); $temp = $start; if ( ($start+$increment_val) <= $end ) { do{ echo " " . $temp . "," ; $temp = $temp + $increment_val; }while ( $temp <= $end ); } else { echo "Can not do This"; } } $start = "1.0"; $end = "1.6"; $increment_val = "0.1"; increment($start, $end, $increment_val); $start = "1.0"; $end = "4.9"; $increment_val = "0.1"; echo "\n"; increment($start, $end, $increment_val); ?> Expected result: ---------------- 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, Actual result: -------------- 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, -- Edit bug report at http://bugs.php.net/?id=26713&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=26713&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=26713&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=26713&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=26713&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=26713&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=26713&r=needscript Try newer version: http://bugs.php.net/fix.php?id=26713&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=26713&r=support Expected behavior: http://bugs.php.net/fix.php?id=26713&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=26713&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=26713&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=26713&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=26713&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=26713&r=dst IIS Stability: http://bugs.php.net/fix.php?id=26713&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=26713&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=26713&r=float
