number or polynomial

• Converts numbers or coefficients of polynomials into elements in finite fields.
• It is used to convert integers or intrgral polynomials int elements of finite fields or polynomials over finite fields.
• An element of a finite field may not have the reduced representation. In such case an application of simp_ff assures the output has the reduced representation.
