Could not able to perform NOT operation in programming calculator

Thank you for taking the time to report this bug. Could you please describe the exact steps you have made to reproduce this issue? I have tried and the NOT operation works for me as expected, however you have to click the NOT button before the number, not after you have entered the number.

Hi Robert Roth,

                  I too have performed the same steps..I clicked NOT
and then 0 I got the result as 10×10⁶³ while I clicked 0 and then NOT
function I got the error message as Malformed function and I too have
tried in different system.But the result is same.
Thanks &Regards,

Hi pradeep, I think it is normal behaviour for gcalctool.
What the parser is intended to do is, process not for expressoin "<NOT> <NUMBER>".
The Not button inserts a <NOT> symbol in text, which is then passed to parser with structure similar like "<NUMBER> <NOT>".
So, what you need to do is press not button before entering the number.

Hope this helps.
