    NPPCalc has issues with recent NPP but anyone stating basic math functions will provide incorrect results is WRONG. Been using it all of 2016 and part of 2015 @rate of 4-6 times a week with all results verified by calculator (& outside financial institution results comparison also). NEVER ONE ERROR from NPP Calc. NB: I only verify with calculator to catch my own possible (transcribing) mistakes. I never give perfect rating cuz there is no software that is perfect. A 4/5 or 9/10 is about as good as any software I have ever seen/used. E.g., NPP Calc has irritating display that makes it put results on separate line, does not add "=" in front and has no menu option in NPP for right-click evaluate that works. Also, I have not used the more advanced functions so could not give it 5|10 anyway. I cannot use it anymore because with NPP 6.9.2 NPPCalc causes display and editing errors. Since NNPCalc has not been updated for a year, I consider it a File 13 plugin.
