Detailed Description

Return true with probability 1/e = exp(−1).

InverseEProb p; p(Random& r) returns true with prob 1/e using von Neumann's rejection method. It consumes 4.572 bits per call on average.

This class illustrates how to return an exact result using coin tosses only. A more efficient way of returning an exact result would be to use ExponentialProb p; p(r, 1.0f);
