#31504 [NEW]: -Infinity value returned for long float nums

From: charlesb at ekit-inc dot com Operating system: sol9 i86, sol8 sparc, sol9 sparc PHP version: 4.3.10 PHP Bug Type: Variables related Bug description: -Infinity value returned for long float nums Description: ------------ Basically we're seeing long floats being given a string value of -Infinity, even if we explicitly cast the variable. Python can handle these vars no problem, don't see why PHP can't? Thanks Reproduce code: --------------- <?php $a = '6.48261999999999982691178956883959472179'; $c = (double) $a; $b = sprintf("%0.2f", $c); print $c.' '.$b; ?> Expected result: ---------------- 6.48261999999999982691178956883959472179 6.48 Actual result: -------------- -Infinity -0N -- Edit bug report at http://bugs.php.net/?id=31504&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31504&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31504&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31504&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31504&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31504&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31504&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31504&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31504&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31504&r=support Expected behavior: http://bugs.php.net/fix.php?id=31504&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31504&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31504&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31504&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31504&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31504&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31504&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31504&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31504&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31504&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31504&r=mysqlcfg
