Miscellaneous tools to deal with polynomials.

clearDenominator: Polynomial Fraction Integer -> Polynomial Integer

clearDenominator(p) multiplies the polynomial p over rational numbers with the least common multiple of all its coefficients and returns the result as a polynomial over the integers.

indexedSymbols: (String, List Integer) -> List Symbol

indexedSymbols(s, l) creates a list of symbols of the form [sx for x in l] where sx denotes the symbol with a name that starts with the string s and ends with the number x.

indexedSymbols: (String, NonNegativeInteger) -> List Symbol

indexedSymbols(s, n) returns indexedSymbols(s, [i for i in 1..n])
