KERML — Exponentiation should be right-associative

Open Closed All
  • Key: KERML-165
  • Status: closed  
  • Source: Dassault Systemes ( Mr. Andrius Armonas)
  • Summary:

    If you look at the following sample:

    1 a = 2 ^ 3 ^ 4;
    2 a = (2 ^ 3) ^ 4;
    3 a = 2 ^ (3 ^ 4);

    Both lines 1 and 2 will generate the same model in SysML v2 pilot implementation.
    This means that exponentiation operator seems to be left-associative, which is unusual, as exponentiation is supposed to be right-associative.
