Calculator on Autocad?

Is there a way to call up a calculator from the autocad menu.
I know there's the system calculator, all the same this option,
if it doesnt' already exist, could be woven into Autocad.

 

For LT: ^C^C_ai_startapp;"calc.exe";
For Full Version: ^C^C(startapp "calc.exe")

 

I am assuming the above is a customisation of
some kind. Can you tell me where i would add
this?

 

It would go in a new custom toolbar button.

You can also reach the built-in calculator in AutoCAD by typing CAL.
It's not pretty but it works, and when used transparently, it can feed the
result directly to a command.

 

wouldn't it be nice if AutoCAD included an feet/inches calculator.

 

In an imperial drawing the native CAL calculator accepts inches and feet.

 

Thanks guys, my new button worked out a treat.

 

AutoCAD 2006 has a great calculator built in. Not as good as my handheld
though.
