OpalCalc is a brand new type of calculator for the PC. As easy to use as Notepad or a word processor, OpalCalc allows natural language in the sum and multi-line support so you can go back and adjust your previous calculations on the fly.
For years, PC calculators have been trying to copy handheld calculators in both functionality and appearance. OpalCalc sets out to disregard previous conceptions, and instead we considered how a calculator should behave with a full keyboard in mind. The result is simplicity itself, but with almost spreadsheet-like capability.
OpalCalc features include percentages, currency conversion, custom functions/variables, excellent documentation, colour coding, lightweight size, configurable GUI, hundreds of measures and functions, and lots more. Give OpalCalc a try to fully assess its capabilities!
NOTE: The full version can be obtained with a donation of any amount.

What's New in This Release:
· There were multiple occasions when a selection of text required a second click, causing frustration (at least subconciously). For example, copy, undo, redo, zoom in/out, copy/clear line, would 'disable' text selection, until you mouse-clicked again. Not any more.
· Spacing between operators has been overhauled. Firstly, spaces can be inserted between operators even if modulus or programmer syntax is enabled. Secondly, spaces can now also optionally be inserted between × and ÷ operators (as well as the old - and +). Thirdly, sums such as "4 + -3" or "test:-5" or "-5 '(beginning of line)" or "pow(3,-2)" won't now insert the unnecessary space before or after the '-' symbol. Fourthly, if quotes are used to comment the beginning or end of the line (; or : or '), then the minus and plus symbols won't now be used in those contexts.
· Functions using the parameter as the exponent now use proper operator precedence. An example would be: "f(n) = 3^n + 1". Calling f(2) now returns 10 instead of...
