Subject: INF behavior
From: philip@roshambo.org (Philip Olson)

Hello geeks,

A geek is needed to clarify PHP bug #45712. This is an edge case but the =
test (bug45712.phpt) contains code similar to the following:

<?php
$inf =3D pow(0, -2);

var_dump($inf);          // float(INF)
var_dump($inf =3D=3D  $inf); // bool(false)
var_dump($inf =3D=3D=3D $inf); // bool(true)
?>

That's how it's behaved since ~forever (AFAICT) and remains in =
5.3.7-dev, but PHP 5.4.0-dev changes behavior so both now return true.

Is this is how we want it? And how should this be documented/explained?

Regards,
Philip
