in reply to Boolean counter?

I tend to use $toggle *= -1;

Update: I stand corrected, thanks LanX. I often use that for alternating rows but it's wrong here.

    well it's a toggle but can't be used as boolean as the OP wanted , since 0*-1=0

    Your idea works the following way - even if it doesn't look as elegant any more:

    $toggle = -1 * ($toggle - 0.5) + 0.5;
