how do i present the variable W with the 2 digits after the decimal point?

i=0.15; v=24;

c=25*10^-6;

R=140; L=260*10^-3;

syms W

eqn = i==v/sqrt((R^2)+(W*L-1/W*c)^2);

W = solve(eqn,W);

w= round(W)

didnt work for me matlab returns W =

   (500*3^(1/2)*5^(1/2))/13 + 6000000026^(1/2)/520
   (500*3^(1/2)*5^(1/2))/13 - 6000000026^(1/2)/520
   6000000026^(1/2)/520 - (500*3^(1/2)*5^(1/2))/13
 - (500*3^(1/2)*5^(1/2))/13 - 6000000026^(1/2)/520

what shell i do?

You may use as well

sprintf('%.2f', W);

[Purushottama Rao]

>> w=1.2345

w =

    1.2345

>> sprintf('%.2f',w)

ans =

1.23

double() the symbolic number to get floating point.
