Rounding
by Micah McCurdy 25 Jan '00

Forgive this simplistic question, but I'm going around the bend. I have an ex, on which I've performed many manipulations, of which I want the value. It's a polynomil in x, and evaluating poly.subs(x==valThatIWant) gives me another ex, which, when output, is the correct number, to 17 decimal places. I need this number as a double value, only to 10 decimal places. What can I do? Setting Digits to various values in various places does not seem to change anything. Any help is welcome.
