#19398 [NEW]: mathmatical errors, especially after string conversions

From: jeffb@umci.com Operating system: Redhat 7.3 PHP version: 4.2.2 PHP Bug Type: Scripting Engine problem Bug description: mathmatical errors, especially after string conversions The script below produces a lot of output on two of our systems. One a 6 cpu ppro, the other a single cpu duron 950. Both boxes run redhat 7.3. One runs the php that came with redhat 7.3, the 6 cpu box runs php 4.2.2 that we compiled ourselves to add more options. For sample output of this script, with a phpinfo() call appended to it, go to: http://www.umci.com/testcode.phtml <? $start=0.01; while ($start <= 10) { // Removing the quotes from test's assignment will eliminate the // errors unless you uncomment the ++/-- down a fiew lines. $test="$start"; $test2=$start; ///////////////////////////////////////////////////////////////// // Uncommenting these two lines accentuates the problem a bit... ///////////////////////////////////////////////////////////////// //$test++; //$test--; if ($test!=$test2) echo "Comparison Result: \"$test\" != \"$test2\" ----- Shouldn't this be true?<br>"; $start = $start + 0.01; } ?> -- Edit bug report at http://bugs.php.net/?id=19398&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19398&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19398&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19398&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19398&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19398&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19398&r=support Expected behavior: http://bugs.php.net/fix.php?id=19398&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19398&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19398&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19398&r=globals
