Calculator is a simple four-function floating-point calculator for BeOS. It accepts input from both the mouse and keyboard, has a memory feature, and supports full Clipboard capabilities. I've included the source in the hope it will help other new BeOS programmers as they write their "tractor" applications. The executable and source code may not be published or otherwise distributed without my explicit permission. I hereby give Be permission to make the files available on the Be web page and FTP site.
