Train Route AND/OR priority

[gacekssj4]

Hello,
Could someone explain me how it exactly works? Can't find any info about it and tried to goole it.

Best on examples:

Code: Select all

true AND true OR true // will eval to true
true AND true OR false // will eval to??
true AND false OR false // will eval to??
true AND false OR true // will eval to?

And/or How is it exactly evaluated

Code: Select all

x AND y OR z

would evaluate as

Code: Select all

(x AND y) OR z 

or

Code: Select all

x AND (y OR z)

and what about

Code: Select all

a AND b AND c OR d AND e

[Loewchen]

It should follow: A || B && C ≡ A || (B && C) meaning AND is evaluated first.

AND is always evaluated before OR.
