Hi,
In fact, I need Sqrt only for the positive cyclotomic numbers.

Hi,
Is it possible to extend the function Sqrt on the cyclotomic numbers?
See below what's happen if we try, for example, with the number E(5) :
gap> Sqrt(E(5));Error, no method found! For debugging hints type ?Recovery from NoMethodFoundError, no 1st choice method found for `Sqrt' on 1 arguments called from<function>( <arguments> ) called from read-eval-loopEntering break read-eval-print loop ...you can 'quit;' to quit to outer loop, oryou can 'return;' to continuebrk>
