(HP15C)(HP67)(HP41C) Bernoulli Polynomials

[John Keith]

Using the formula d = Product p, (p-1) | m from your 2nd link in post #19 along with approximate values of B(n) computed by tangent numbers, we can get exact a up to B(28) with 12 digits, or B(26) with 10 digits. Of course, we then need a way to compute divisors of m and primes or GCD, which no HP calculator before the HP49 has. There are good factoring libraries for the HP-48 but this would not be easy for keystroke programmable calculators.
