Struct WinningProbability

pub struct WinningProbability(/* private fields */);

Expand description

Represents a ticket winning probability.

It holds the modified IEEE-754 but behaves like a reduced precision float. It intentionally does not implement Ord or Eq, as it can be only approximately compared.
