php numbers: assert( 1.0 < 2.0 )

How can this

<?php
assert( 1.0 < 2.0 );
?>

result in

Warning: assert() [function.assert]: Assertion failed in C:\Program Files (x86)\wamp\www\test.php on line 2

Edit: depending on the file I put this code in, 1.0 <开发者_运维问答 2.0 evaluates to false or true.

Try writing it as a string instead. :)

assert("1.0 < 2.0");
