postfix notation
(Or "Reverse Polish Notation", RPN) One of the
possible orderings of {functions} and {operands}: in postfix
notation the functions are preceded by all their operands.
For example, what may normally be written as "1:2" becomes "1
2 :". Postfix notation is well suited for {stack} based
{architectures} but modern {compilers} reduced this advantage
considerably. The best-known language that with strictly
postfix syntax is {FORTH}.
Compare: {infix notation}, {prefix notation}.
