RE: i need a small prog to calculate a MATH expression

ANY math expression?

I had an idea once on how to process a math expression although unfortunately it works only if all the operators are *left-to-right* associative.  It involves using a stack; if the next operator is higher precedence, the current operator is pushed on the stack, and the next operator is taken; if the next operator is lower precedence, then the current operator is performed.  If an open parenthesis is encountered, the expression evaluator calls itself and forms a new stack structure; if a close parenthesis is encountered the evaluator returns to the parent evaluator.
