Description

• 

The Normal function is a placeholder for representing a normal form for an expression. It is used in conjunction with mod and evala as described below which defines the coefficient domain.

• 

The call  Normal(a) mod p computes a normal form for a where a is a rational expression over a finite field.

• 

The call  evala(Normal(a))  computes a normal form for a where a may contain algebraic coefficients defined by RootOfs or radicals. See evala,Normal for more information.
