Acctually, $test is assigned $number regardless of what $number is ... if you do any mathematicly operations on a scalar which is "not a number" then that scalar is evaluated as "0" (and a warning is generated).

Which was basicly my point ... the whole premese of this test is flawed. (uless you set up a signal handler for warnings, which causes a "die" to be thrown)
