Rational Fractions in Symbolic Toolbox

When I finish the algebraic manipulations using the symbolic toolbox and start putting numbers into variables I always end up with clunky rational fractions such as

           / 890915281312783 x \ 
    733 sin| ----------------- | i 
           \  281474976710656  / 
  - ------------------------------ 
               80000000

Is there a way to make this look like

 9.1625e-006 sin(3.1652 x ) i     ?

 Thanks.

Sorry. I found the answer to my question...vpa (should have known this).

hi,

i have the same problem

how did you solve it?

when i write symbolic, i get big fractions and when they go to vpasolver, the calculation takes long so i want the fraction to be a number with 3 decimal digits.
