problems with float

Interesting. indeed, exp(exp(2)),numer works.

I'm not sure I understand the syntax though, what does the coma means here? 
It is the first time I see this construct.

Also, shouldn't float(exp(exp(2))); work? Anyone can see why it shouldn't 
work?

As far as syntax is concerned, I'd like to ask a related question, if I type  
integrate(x*log(x),x,1,y);, then I'm being asked if y-1 is positive...  
That's the proper behavior, but can't I just write it on a command line, like

integrate(x*log(x),x,1,y), assume y-1 positive;

Something like this?


>>>
I think this can be done by
exp(exp(2.0))

or  exp(exp(2)),numer;

It seems to me that this facility is not
quite right though.
