New Comment:
That is an expected behavior.
The strval() isn't required to you get this result, the echo statement,
var_dump(), and etc will print the value according to the precision
setting.
Thanks.

Addition to the bug report: I tracked the issue down to the "precision"
setting in php.ini. When set to "4", when strval() receives a number
with 4 digits to the left of the decimal point, the output will only be
a string og 4 digits. E.g. strval(1001.1) returns "1001". The
documentation for "precision" setting says:
"""
precision integer
The number of significant digits displayed in floating point
numbers.
"""
It doesn't mention strval() (and strval() manual page doesn't mention
"precision") and it's a bit ambiguous.
(the behaviour is the same on Linux and FreeBSD).

Description:
------------
Calling strval() on certain floating point numbers (not all) on FreeBSD
sometimes inexplicably truncates or rounds the result. Checked on both
FreeBSD 6.3 and 7.0. Works fine in Linux.
Reproduce code:
---------------
<?php
$v = 4867.8;
echo strval($v);
?>
Expected result:
----------------
"4867.8"
Actual result:
--------------
"4867"
