Converting a symbolic array to a double array cuts off decimal places, why?

I have a symbolic array arrsym with values like for example 1.234567891234567...

When I double(arrsym), then I get only four decimal digits, so I get 1.2345 in my new double array instead of the corresponding 1.234567891234567 in my old symbolic array ...

How can I keep all the dicimal digits of my numbers in the symbolic array also after conversion of this symbolic array into a double array?

Thank you for your answer in advance.

You have only 4 digits displayed, but they are really full double precision variables in memory with about 15-16 decimal digits of precision.
