Modifier and Type	Method	Description
`BigIntPolynomial`	`mult(BigIntPolynomial poly2)`	Multiplies the polynomial by a `BigIntPolynomial`, taking the indices mod N.
`IntegerPolynomial`	`mult(IntegerPolynomial poly2)`	Multiplies the polynomial by an `IntegerPolynomial`, taking the indices mod `N`.
`IntegerPolynomial`	`mult(IntegerPolynomial poly2, int modulus)`	Multiplies the polynomial by an `IntegerPolynomial`, taking the coefficient values mod `modulus` and the indices mod `N`.
`IntegerPolynomial`	`toIntegerPolynomial()`	Returns a polynomial that is equal to this polynomial (in the sense that `mult(IntegerPolynomial, int)` returns equal `IntegerPolynomial`s).

- Method Detail
  - mult
```
IntegerPolynomial mult(IntegerPolynomial poly2)
```
    Multiplies the polynomial by an IntegerPolynomial, taking the indices mod N.
    
    Parameters:
    
    poly2 - a polynomial
    
    Returns:
    
    the product of the two polynomials
  - mult
```
IntegerPolynomial mult(IntegerPolynomial poly2,
                       int modulus)
```
    Multiplies the polynomial by an IntegerPolynomial, taking the coefficient values mod modulus and the indices mod N.
    
    Parameters:
    
    poly2 - a polynomial
    
    modulus - a modulus to apply
    
    Returns:
    
    the product of the two polynomials
  - toIntegerPolynomial
```
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:
    
    a new IntegerPolynomial.
  - mult
```
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 - the polynomial to multiply by
    
    Returns:
    
    a new polynomial
