exp4j is a small Java library for evaluation of mathematical expressions. It implements Dijkstra's Shunting-yard algorithm to translate expressions from infix notation to Reverse Polish notation and calculates the result using a simple Stack algorithm. ==Features== * Variables can be used in expressions * exp4j comes with a set of common built-in functions * Users can create and use their own custom operators * Users can create and use their own custom functions 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Exp4j」の詳細全文を読む スポンサード リンク
