Format a large number into small decimal number

Hello,

I have code on function like:

hr = sqrt ( .1/ 2 ) .* (h_i+j*h_q);

hr1 = sqrt (.3/ 2 ) .* (h_i+j*h_q);

x=x = constellation(randi([1 4],50));

syms cr;

r=(hr*x+hr1*cr);

and I am getting the answer like cr*(2031273339923201/4503599627370496 - 7019058886806809i/36028797018963968) - 42472189963858493/288230376151711744)

How I will format this large number into small decimal number?

Lookup matlab built-in functions like simplify() or vpa().

This should do the work:

vpa(r, 4)
