Division-by-Zero Calculator Using Semi-structured Complex Numbers

A **semi-structured complex number** has the form `h = x + yi + zp` andis represented as the ordered triple `(x, y, z)`. The unit `p = 1/0`is the designated absorbing element that arises from division by zero. Two calculators are implemented: | Calculator | Division-by-zero handling ||------------|--------------------------|| **STD** | Exception (`ZeroDivisionError`) — equation aborts || **DBZ** | Totalized algebra — divisor replaced by `p = (0,0,1)`, computation continues | Both share the same infix-to-postfix converter and postfix evaluator.They differ only in their Arithmetic Machine.
