MATLAB: How to shorten the output of a system of equations

Question

Hi! I am trying to solve a system of equations like the one below.

u = sym('u');
v = sym('v');
w = sym('w');
a = sym('a');
eqn = [u + i*v == 0, u + v*exp(i) + w == 3, w == a];
[sol_u, sol_v, sol_w] = solve(eqn, u, v, w);

The output I get for sol_u is

sol_u =

9646051260569284469454035484672/6430700840379523962456038802037 – a*(3215350420189761489818011828224/6430700840379523962456038802037 – 10958632677415100254319546466304i/6430700840379523962456038802037) – 32875898032245300762958639398912i/6430700840379523962456038802037

I tried using:

sol_u = double(sol_u);

But MATLAB gives me an error saying "Error using symengine, Unable to convert expression into double array."

How can display the output of these equations in a shorter format(i.e double)?

Thank you.
