what is the prober method to convert big.int from gmp to big.int from "math/big"

[msh2050]

I get Cannot use 'nouse.FastDoubling(n)' (type *"github.com/ncw/gmp".Int) as the type *"math/big".Int

this will happen if you want to import from another package...

after some tests
I think the fastest method is to use :

        bigmath := new(big.Int)
	bigmath = bigmath.SetBytes(gmp.Bytes())
