Synopsis:
    Log-domain floating point numbers
Description:
    This module presents a type for storing numbers in the log-domain.
    The main reason for doing this is to prevent underflow when
    multiplying many probabilities as is done in Hidden Markov
    Models. It is also helpful for preventing overflow.

-- This should work as far back as GHC 7.6.1, but we don't verify that by CI.

Flag useFFI
    Default:     True
    Description:
        Use FFI to link C's log1p. Improves accuracy while maintaining
        the same performance. Disable only if your compiler doesn't
        support FFI.
