Struct WinningProbability 

pub struct WinningProbability([u8; 7]);

Represents a ticket-winning probability.

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

Tuple Fields

0: [u8; 7]
