OpalCalc is a brand new type of calculator for the PC. As easy to use as Notepad or a word processor, OpalCalc allows you to insert natural language as part of the sum, along with multi-line support so you can go back and adjust your previous calculations. Want a tiny footprint on the screen for a single sum? Resize accordingly. Want it to fill the screen for heavy-duty work? OpalCalc can adapt. Featuring a lightweight footprint, on-the-fly calculation as you type, percentages, variable support, hundreds of units and functions, extensive notation support, intuitive design/documentation and much more. Once you've tried it, you'll never want to go back to your ordinary desktop (or PC) calculator again!
