AllerCalc for Windows

The best calculator ever for frequent usual mathematics. If you keep you handheld scientific calculator near by you you can't find better. you can hide the keyboard and keep only your calculation historic and modify at will your past calculations and get the new result. you type your calculation line with the functions you need "excel wise" and hit "enter" you get your result. if after lunch you just forget where you put your note with what it give. just open Allercacl and you get everything you did unless you clear your screen even after reboot. Once I new I made the calculation the week before and couldn't remember what were the number... guess what I rolled back got my calculations change few numbers by new one and got my new result without the head-hack!!! THE BEST!!! I'm engineer and be using it since more than 10 years now.And I forgot... no need to install it, just double clic and here you go...there is also unit converters and hex and other thing but as windows 10 do not allow anymore to read help files it's a bit harder to begin using it since you need to know the specific name of the function and therefore idle a while before finding the right ones...if someone could get the code and update this wonder i would pay for it!!! double rate!!! for the time it saved me over my life.

Uninstalled it after just a few minutes. 1) no easy way to flip between decimal and hex. you have to drop down the options list and click to get to another drop down to chose Decimal, Hex, binary, octal etc. Should at least be a pf key to flip between dec and hex (as MS's calc does). After all this is a hex calc!2) no key to clear display. ESC minimizes it. once again drop down menu and click Clear Display (CLR).3) conversion of a negative decimal number into hex gave different results with each try. None were correct.4) starts up with a 'finance window'. Drop down option to show it or not does nothing. you have to X close it to get rid of it.5) Download blew away IE. Looked up and it was gone. Restarted and it said it closed unexpectedly etc.6) Uninstall left AllerCalc dir with files in it and a registry entry too. Pros: NONE Cons: See above. that was only a few minutes
