Shorty and/or Operators

[jleesaxon]

I'm confused about the interaction of and/or operators and parentheses.

 

My understanding is that && is higher priority than || which is priority than AND, so

 

{$A && $B && $C || $D && $E}

means "(A and B and C) or (D and E)", while

 

{$A AND $B && $C || $D && $E

means "A and ((B and C) or (D and E))." But aren't parenthesis even higher priority than &&, meaning that

 

{$A && ($B && $C || $D && $E)}

also means "A and ((B and C) or (D and E))"? Doesn't that mean that

 

{$A AND ($B && $C || $D && $E)}

is redundant?

I believe parenthesis are not redundant in this case as you want to have A and b&c OR d&e, seems logical to me
