On a standard Arduino, you can't, because doubles are not supported (the keyword "double" is treated the same as "float").

Use of Strings is not recommended on the standard Arduino, as they cause memory problems and program crashes.

Do you want like this?

In UNO :

float x;
x = 11.8563563753653545638;

or

double x;
x = 11.8563563753653545638;
