Arithmetic evaluation: Difference between revisions

Note that once you get beyond a few basic arithmetic operations, what we commonly call "mathematical precedence" stops making sense, and its primary value is that it allows polynomials to be expressed simply (but expressing polynomials as a sequence of coefficients, one for each exponent, is even simpler).

 

 

The implementation here uses a shift/reduce parser to build a tree structure which J happens to support for evaluation:
