Display symbolic expressions as rational.

How can I display symbolic expressions as rationals? Functions like sympref or vpa allows to display in decimal format, but doesn't provide a way to display symbolic expressions as rationals.

For example:

syms x
(1/2)*(3*x^2)
 
ans =
 
1.5000*x^2

Instead of that output I desire the rational expression (or similar):

(3*x^2)/2

That's what I get:

>> syms x
(1/2)*(3*x^2)
ans =
(3*x^2)/2

Do you have something set in preferences that is forcing the decimal output?

syms x
sympref('FloatingPointOutput',true);
(1/2)*(3*x^2)

ans = 

sympref('FloatingPointOutput',false);
(1/2)*(3*x^2)

ans =
