gives the value of the discrete exponential of n associated with the field f.
- To use FieldExp, you first need to load the Finite Fields Package using Needs["FiniteFields`"].
- With p a primitive element of the field f, the value of the discrete exponential function of n is pn. In particular, FieldExp[f,1] gives the primitive element used.
- FieldExp is defined only if PowerListQ has been set True for the field.
- FieldExp[f,-∞] gives 0.
