Please pardon the mathematical naivete: I passed -18 to mpz_pow_ui and
the code crashed. No surprises there ("read the friendly manual, you
goose!") So I went back to the manual and tried to get my mind around
mpz_powm and related things. I'm still as confused as before. Please,
someone, take pity on me and demonstrate in a bit of C how to raise 2 to
the negative 18.
