FTR.

If you have Maple 11 just right click at the end of your biggish expression , get a long drop down menu, choose <Evaluate at a point>, plug in your point and get an exact answer.  If the answer is  not a single real number, right click again and choose <Approximate>, <5 digits>.

The Maple output is elegant and informative.

Here is an example that is not elegant nor informative,FWIW.

 E := sin(x)+x; @ x=4, = sin(4) + 4 = 3.2423, all done with right clicks but without the long arrows and informative superscripts.                                

Thanks, your point about float well taken. Although your answer didn't help me on "Help" it did give me the answer I was looking for. I didn't know that you could put [ ] outside the command. This could be a useful example in "Help" somewhere, don't you think (rhetorically that is)?

What is the Straight Dope on "digits"? > evalf(Pi); digits := 4; evalf(Pi), "Not 4 digits?"; evalf(Pi, 5); digits, "So why is it still 10 digits?"; 3.141592654 4 3.141592654, "Not 4 digits?" 3.1416 4, "So why is it still 10 digits?"

BYC * I am having trouble finding help in Help for making a list of points such as [[a1, sin(a1)], [a2, sin(a2)], .. [an, sin(an)]], where a1=0 and an=a10=Pi. That's a 20 degree interval. I can get a column of points but not a row list of points. asa * Begging Your Compassion
