Funny. Think I spotted a minor hiccup in this calculate. Looked to where it could be reported. Got redirected to a site where you (NOW) need to pay to have an account. ... Not sure how that's going to work for public-domain software. (And No!, I'm not going making a trial account for that, or for just about anything else for that matter.)
Жаль, что не переводит между системами счисления, как KCalc или штатный в старой Wind'е (новой не пользуюсь) - из шестнадцатиричной в двоичную и т.д..
I had bad output from it... try 280000000 x 0.005% = and it gives unreliable result. I had to use my android with google on it to calculate properly.
