This package provides a type for storing numbers in the log-domain, primarily useful for preventing underflow when multiplying many probabilities as in HMMs and other probabilistic models. The package also provides modules for dealing with floating numbers correctly.

I am currently working on http://hub.darcs.net/thielema/hmm-hmatrix It does not need log-numbers because it normalizes all temporary results. This way I can use fast hmatrix operations. Would normalization also be a solution for other probabilistic models?
