OpalCalc is a powerful calculator that 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. It features a lightweight footprint, on-the-fly calculation as you type, percentages, variable support, hundreds of units and functions, extensive notation support, intuitive design/documentation.
v1.7 [Jun 23, 2014]
- Very small numbers combined with measurement units were previously scrambled when referenced. Example: Something like "0.00001 miles" would produce an error or incorrect figure when used in a future calculation (referenced as a variable, answer, total etc.). This awful bug has now been fixed for good.
- Sums such as "5/4cm" will now result in "1.25 cm" rather than "1.25 /cm". The latter is more technically correct as the sum was originally treated as "5/(4cm)", but it is now treated as "(5/4)cm" which is how most people will interpret it. If you're ever unsure, always use brackets to be on the safe side.
- You can now log sheets to disk upon closing of Opalcalc. Useful for storing all past calcs automatically. To open the text log file, go to Options (window) -> "Open user path" (button) -> "calc-log.txt" (file).
- Single parameter functions by themself on a line will calculate the answer to the previous sum automatically. For example "9", followed by "sqrt" on the next line will result in 3 without having to type "sqrt(ans)".
- In the "Custom Notation options" window, GUI elements are now automatically disabled/enabled according to what's relevant.
- The buttons "Open prog path" and "Open user path" and have been added to the Options window. The latter is omitted in the portable version as they both equal the same folder.
