P() | = | (prior probability of ) | ||

P(|) | = | (probability of given ) | ||

P(|¬) | = | (probability of given ¬) | ||

P(|) | = | (posterior probability of given ) | ||

P(|¬) | = | (posterior probability of given ¬) |

Both decimal and % probabilities are supported.

This uses `BigDecimal`

, not floating point math. It still loses bits with non-terminating decimals, though.
