From: ehanneken at pobox dot com Operating system: PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Floating point grammar omits signed numbers
Description: ------------ According to the manual (http://www.php.net/manual/en/language.types.float.php), the following grammar specifies floating point numbers: LNUM [0-9]+ DNUM ([0-9]*[\.]{LNUM}) | ({LNUM}[\.][0-9]*) EXPONENT_DNUM ( ({LNUM} | {DNUM}) [eE][+-]? {LNUM}) This leaves out signed numbers. The grammar should be written as something like ULNUM [0-9]+ SLNUM [+-]{ULNUM} DNUM [+-]?(([0-9]*[\.]{ULNUM}) | ({ULNUM}[\.][0-9]*)) EXPONENT_DNUM [+-]?( ({ULNUM} | {DNUM}) [eE][+-]? {ULNUM}) Reproduce code: --------------- echo gettype(-3.14) . "\n"; echo gettype(+3.14); Expected result: ---------------- double double Actual result: -------------- double double -- Edit bug report at http://bugs.php.net/?id=40996&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40996&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40996&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40996&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40996&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40996&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40996&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40996&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40996&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40996&r=support Expected behavior: http://bugs.php.net/fix.php?id=40996&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40996&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40996&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40996&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40996&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40996&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40996&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40996&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40996&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40996&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40996&r=mysqlcfg
