Documentation

wordMax :: Integral a => a

return the maximum value storable in a Word

wordSize :: Int

return the bitSize of a Word

sizeinWords :: Int -> Int

determine the needed storage for a bitlength in Words

log2len :: Integer -> Int

returning the binary length of an Integer, uses integer-gmp directly

testcond :: Word -> Int -> Word

we want word w at position i to result in a word to multiply by, eliminating branching
