That's what I think too :)

I am using a calc tool too - not the win's calc, but KCalc under Suse. Anyway,
the point is the same - it's always good to have a simple "calc" tool, no
matter under which OS.

I tried to keep FoxCalc as simle as I could, without such "expert" things (I
added MOD just because it was trivial to do so). Personally, I never use
functions like sin/cos/tan etc, so I don't feel such need...
the "1E06" notation is automatic when when the display number gets to high.
Brackets are pretty hard to implement now, as I designed FoxCalc from the
begin as a replacement for all those cheap hand calculator, so it have the
memory for only 2 numbers (the result + currentWorkNumber)...
In fact, the only time in my life when I needed such scientific calculations
was when I was at the university... I think that if someone needs an advanced
calculator, he should rather look after CALC387 or FDRC...

Right, that could be okay... I should implement that before the 1.0 version.

You're wrong. FoxCalc checks those conditions, and if division by zero or
square negative, it returns "Inf".

I didn't checked that before... :(
I will have to fix that soon.

I'm waiting to see if I got some similar answers (so far, I got only two
answers, including yours...). If no interest from other FreeDOS user's, I
will just stay with FoxCalc...
