Right-associative
In programming language theory, the associativity of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses. If an operand is both preceded and followed by operators (for example, ^ 3 ^), and those operators have equal precedence, then the … See more Associativity is only needed when the operators in an expression have the same precedence. Usually + and - have the same precedence. Consider the expression 7 - 4 + 2. The result could be either (7 - 4) + 2 = 5 or 7 - (4 + 2) = 1. … See more Non-associative operators are operators that have no defined behavior when used in sequence in an expression. In Prolog the infix operator :- is … See more In many imperative programming languages, the assignment operator is defined to be right-associative, and assignment is defined to be an expression (which evaluates to a value), not just a statement. This allows chained assignment by … See more • Order of operations (in arithmetic and algebra) • Common operator notation (in programming languages) See more WebSome logical operators are associative: both ∧ and ∨ are associative, as a simple check of truth tables verifies. Likewise, the biconditional ↔ is associative. However, the implication …

WebIf op is right-associative and its parameter is passed by value, it is interpreted as { val x=e1; e2.op (x) }, where x is a fresh name. This means that all by-value parameters are still forced from left to right but by-name parameters are not forced anymore. They now behave the same way in operator syntax as they would when using standard ...
In mathematics, the associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs. Within an expression containing two or more occurrences in a row of the sam…

WebAug 23, 2016 · Right exponentiation associativity works like this: 2^2^3 == 2^ (2^3) == 256. Many people would say that right associativity is more useful since (a^b)^c == a^ (b*c) anyway.
