Simplifying numbers in symbolic function

Upon substituting into a symbolic expression I get very long analytic expressions for numbers, e.g. (2^(1/2)*(3^(1/2)*pi*(5^(1/2)/4 - 1/4)*(1/120000 + i/6000000)t + .... is there any way to simplify these numbers down to a single double precision complex number in the symbolic expression to make for easier viewing? I can't just use double (expression) as it still have a symbolic variable.

Many thanks.

David, have you tried vpa(expr)?

 syms x t
 x = 2^(1/2)*3^(1/2)*pi*(5^(1/2)/4 - 1/4)*(1/120000 + i/6000000)*t;
 vpa(x,10)     % you can adjust the number of significant digits
 ans =
 t*(0.00001981648468 + 0.0000003963296937*i)

That seems to be what I was looking for
