There was a bug in my revised grammer, too. How about this?
ULNUM [0-9]+
SLNUM [+-]{ULNUM}
DNUM [+-]?(([0-9]*[\.]{ULNUM}) | ({ULNUM}[\.][0-9]*))
EXPONENT_DNUM ( ({SLNUM} | {DNUM}) [eE][+-]? {ULNUM})

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
