Bug Type: Math related
Operating System: Solaris / nsapi
PHP Version: 4.3.8

New Comment:
seems to be related to the following addition to config.m4
dnl Solaris 2.8 claims to be 2004 API, but doesn't have
dnl ldap_parse_reference() nor ldap_start_tls_s()
AC_CHECK_FUNCS([ldap_parse_reference ldap_start_tls_s])
a HAVE_... macro for ldap_start_tls_s was added to config.w32
but it looks as if ldap_parse_reference was overlooked
at least according to MSDN windows supports
ldap_parse_reference just fine
i can't compile and test on windows so i'll add the
required patch here for now:

Description:
------------
When I perform floatingpoint calculations I get really unexpected
results.
The next three examples should all give 1 as result but they all give 0
as result.
echo "floatval \"0.5\"*2=".floatval((2*"0.5"))."<br>";
echo "floatval \"0,5\"*2=".floatval((2*"0,5"))."<br>";
echo "\"0.5\"*2=".(2*"0.5")."<br>";
I found that this could be locale related and so I tried adding just
above the previous code:
$local=setlocale(LC_ALL,"nld_nld");
echo "<p>Country set to: \"nld_nld\": ".$local."<p>\n";
(or $local=setlocale(LC_NUMERIC,"C"); )
Now when I run the script for the first time after a server start up
this will give:
Country set to: "nld_nld": Dutch_Netherlands.1252
floatval "0.5"*2=1
"0.5"*2=1
0.5*2=0
Still the last one is incorrect.
To make it even weirder, when I hit reload to run the script again it
will give:
Country set to: "nld_nld": Dutch_Netherlands.1252
floatval "0.5"*2=1
"0.5"*2=1
0.5*2=1
and that is correct!!
So every time after a server startup (SunOne webserver with php running
as nsapi) I have to run a dummy script to change the locate in order for
floatingpoint calculations to be performed correctly in scripts that are
run after that.
In the past we used older versions of PHP (4.2.x) and those versions
did not have this problem. We did run the older versions as CGIBIN
under a Netscape Enterprise server but that is not possible anymore
with the newer versions so I can't test if it is a result of running
PHP as NSAPI now.
Is this a know bug and is there a good workaround?
Reproduce code:
---------------
$local=setlocale(LC_ALL,"nld_nld");
echo "<p>Country set to: \"nld_nld\": ".$local."<p>\n";
echo "floatval \"0.5\"*2=".floatval(2*"0.5")."<br>";
echo "\"0.5\"*2=".(2*"0.5")."<br>";
echo "0.5*2=".(2*0.5)."<br>";
Expected result:
----------------
Country set to: "nld_nld": Dutch_Netherlands.1252
floatval "0.5"*2=1
"0.5"*2=1
0.5*2=1
Actual result:
--------------
(without the setlocale:)
floatval "0.5"*2=0
"0.5"*2=0
0.5*2=0
or
Country set to: "nld_nld": Dutch_Netherlands.1252
floatval "0.5"*2=1
"0.5"*2=1
0.5*2=0
or when teh script is run a secondtime:
Country set to: "nld_nld": Dutch_Netherlands.1252
floatval "0.5"*2=1
"0.5"*2=1
0.5*2=1
