POLY.RED MLG July 82 -------- POLY is a simple (pedagogic) Rational Function Evaluator. After loading POLY.RED, run function ALGG(); or RAT(); These accept a sequence of expressions: <exp> ; | QUIT; (Semicolon terminator) <exp> ::= <term> [+ <exp> | - <exp>] <term> ::= <primary> [* <term> | / <term>] <primary> ::= <primary0> [^ <primary0> | ' <primary0> ] ^ is exponentiation, ' is derivative <primary0> ::= <number> | <variable> | ( <exp> ) It includes a simple parser (RPARSE), 2 evaluators (RSIMP x) and (PRESIMP), and 2 prettyprinters, (RATPRINT) and (PREPRINT) PREFIX Format: <number> | <id> | (op arg1 arg2) + -> PLUS2 - -> DIFFERENCE (or MINUS) * -> TIMES2 / -> QUOTIENT ^ -> EXPT ' -> DIFF Canonical Formats: Polynomial: integer | (term . polynomial) term : (power . polynomial) power : (variable . integer) Rational : (polynomial . polynomial)
