Creating output for quadradic roots that displays i if imaginary

I am trying to get this to display the imaginary values with an i after them in the output. Any suggestions?

function quadroots(a,b,c)

%function to calculate the roots of a quadratic function given a, b, c

%2/25/21

%AE 227

z=discrim(a,b,c);

if z<0

z=z*-1;

end

w1=(-b+sqrt(z))/(2*a);

w2=(-b-sqrt(z))/(2*a);

fprintf('The roots are: %.0f, %.0f.\n',w1,w2);

end

Hi

You may find Matlab "roots" useful to find roots of quadratic equation.
