Use FFI to link C's log1p. Improves accuracy and same performance. Disable only if your compiler doesn't support FFI.
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.
