[GAP Forum] Solving Cubic and Quartic Equations in GAP

Dear GAP Forum,

As far as I know, real and complex numbers are not supported by GAP.
For rational polynomials I have implemented a package containing a function to 
express the roots of the polynomial by radicals if this is possible. You can 
find the package under
