Question

After using the ‘solve’ function on an equation with one variable, it seems like Matlab doesn’t like using floating point. So, my answer is

ans = -2515439103678008769411809280/29019457930552314063110978530889-1/232155663444418512504887828247112*13479465975722384794797850090594238631144539220477565900842902305^(1/2) 

and I’m not sure what the best way to convert it to an understandable decimal is. The best way I have so far is

eval(char(ans)) 

(which gives me -0.5002 for those keeping track), but I’m not really happy with that solution.

Can anyone suggest something better?

Answer 1

Well, the very next page I looked at had the answer. It’s the ‘double’ function:

double(ans)
