Typo: I used the below as you stated and got \"false true\" not the double true you said I would.
//echo -a $iif(1 !<= 0,true,false) $iif(1 > 0,true,false)
Edit: I would also like to note I have not rated it so any change to the score , up or down , is not my doing. When I rate I will note doing so in a post.
