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!

What's new in this version:
- If nothing's selected, Ctrl+C now copies the current answer to the clipboard (or last answer if current is blank).
- If nothing's selected, Ctrl+X now copies the current sum to the clipboard (or last sum if current sum is blank).
- The "Prefs -> Autosave prefs on exit" setting is saved after adjustment without the user having to save at that point.
- As a special case, Opalcalc now handles remainders. Use x/y and then add "rem" on the end (without the quotes). Example: "7/3 rem" would equal "2 rem 1".
- The 'copy' button now works if any of the output is selected (only input worked before)
- Printing now remembers the saved margins without needing to open the Page Setup dialog.
- Added new functions to convert from and to Kelvin: f2k(), k2f(), k2c(), c2k()
- Added different type of 'cups' as a volume measurement
- Cursor moves to end of document when opening a file.
