float(39)
float(17)
float(-17)
float(-39)
float(39)
float(17)

Description:
------------
Typecasting or converting some numeric strings variables to a float
value does not work as expected.
Reproduce code:
---------------
$var = (float)"-39.000";
var_dump($var);
$var = (float)"39.000";
var_dump($var);
$var = (float)"17.000";
var_dump($var);
$var = (float)"-17.000";
var_dump($var);
$var = "-39.000" + 0;
var_dump($var);
$var = "39.000" + 0;
var_dump($var);
$var = "17.000" + 0;
var_dump($var);
$var = "-17.000" + 0;
var_dump($var);
Expected result:
----------------
float(-39)
float(39)
float(17)
float(-17)
float(-39)
float(39)
float(17)
float(-17)
Actual result:
--------------
float(-38.:)
float(38.:)
float(16.:)
float(-16.:)
float(-38.:)
float(38.:)
float(16.:)
float(-16.:)
