Do the sqrt(number in sym form) give a result with real number like 2.3456.

I use very large number 2^1024 and more. I define my numbers and variables by sym form like sym(K). The problem when I use sqrt function with number or variables of sym form. As an example if I want to sqrt(K) and K is sym type and it 's value is 205 the answer I get 205^1/2 instead of 14.317821063276353154439601231034 which I need the last value in my calculation. Is there a solution to a this problem

Yes, there is.

Use the vpa function:

x = sym(sqrt(205))
xn = vpa(x)

xn =
14.317821063276353154439601231034
