Description:
------------
I am developing a tool which parses header information etc. were using 5.3.1 and cant really upgrade at the snap of a finger due to management limitations. One line in the message is $levels.  This contains a bunch of floating point numbers which i will need to compare to other floating point numbers.  I have a table where this floating int is 'echoed'.  When it is echo'd, numbers to the left of the decimal appear as a symbol character. Once the page is refreshed, the numbers to the left of the decimal are displayed correctly. (real example '?.15998') as soon as its refreshed, 20.15998 is shown as expected.

I thought if i changed the $scorefinal back to a string it would resolve but it does the same thing.  Any thoughts?

Test script:
---------------
echo $levels;   //$levels= (S:20.15998/99.90000 CV:99.9000 FC:95.5390 LC:93.6803 R:95.9108 P:95.9108 M:97.0282 C:60.2565 )..



$scorefinal = strstr($levels,"S:");
$scorefinal = strstr($scorefinal,"/",true);
$scorefinal = substr($scorefinal,2);    
//echo $scorefinal;                        //this now is a string and is 20.15998
$scorefinal = 0 + $scorefinal;             //convert to float
$scorefinal2 = "$scorefinal";              //20.15998 is now a string again

Expected result:
----------------
I expect to see the full floating int every-time the page is called.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

<?php

$stringstart = "91.65894";  #initally i get these numbers as strings
$converttofloat = 0 + $stringstart; # i convert them to float by doing this

$vartype = gettype ($converttofloat);

echo $converttofloat . " is this type of variable: " . $vartype;

?>

That script here outputs:

"91.65894 is this type of variable: double"

What do you get?
