01:42 <cached> I know that this sounds like a stupid question, but how do I get a function to evaluate at a certain value?

01:43 <cached> like if i have x^2+3x+2, how do I get it to evaluate that at x=4?
01:44 <cached> and then give a decimal value
01:46 <lindi-> cached: ev(x^2 + 3*x + 2, x = 4);
01:46 <cached> oo
01:46 <cached> thanks

01:58 <cached> how do I display the decimal value of a number
01:58 <cached> like 1.414... instead of sqrt(2)
02:02 <Prax01D> sqrt(2),numer;
02:03 <cached> thanks

10:40 <rhz> Suppose I have some expression. How do I ask maxima to evaluate it to 10 decimal places?
12:34 <tapas> rhz: i think using bigfloats and then reducing the output precision
12:34 <tapas> don't ask me how to do that though ;)

14:28 <HaraldG> For ten decimal places the usual double floats work well.
