public BigIntPolynomial mult(BigIntPolynomial poly2) Multiplies the polynomial by a `BigIntPolynomial`, taking the indices mod N. Does not change this polynomial but returns the result as a new polynomial. Both polynomials must have the same number of coefficients. Parameters poly2:BigIntPolynomial the polynomial to multiply by Returns:BigIntPolynomial a new polynomial

public BigIntPolynomial mult(BigIntPolynomial poly2)

Multiplies the polynomial by a BigIntPolynomial, taking the indices mod N. Does not change this polynomial but returns the result as a new polynomial.
Both polynomials must have the same number of coefficients.

Parameters

poly2:BigIntPolynomial: the polynomial to multiply by

Returns:BigIntPolynomial

a new polynomial

toIntegerPolynomial	back to summary
public IntegerPolynomial toIntegerPolynomial() Returns a polynomial that is equal to this polynomial (in the sense that `mult(IntegerPolynomial, int)` returns equal `IntegerPolynomial`s). The new polynomial is guaranteed to be independent of the original. Returns:IntegerPolynomial a new `IntegerPolynomial`.

public IntegerPolynomial toIntegerPolynomial()

Returns a polynomial that is equal to this polynomial (in the sense that mult(IntegerPolynomial, int) returns equal IntegerPolynomials). The new polynomial is guaranteed to be independent of the original.

Returns:IntegerPolynomial: a new IntegerPolynomial.
