作为probability_to_friendly_string crate发布。

需要Ruby 2018版本

用法

use probability_to_friendly_string::FriendlyProbability;

let friendly = FriendlyProbability::from_probability(0.723);
assert_eq!(5, friendly.numerator());
assert_eq!(7, friendly.denominator());
assert_eq!("Good chance", friendly.friendly_description());
assert_eq!("5 in 7", friendly.friendly_string());

let friendly = FriendlyProbability::from_probability(0.999);
assert_eq!(">99 in 100", friendly.friendly_string());

let friendly = FriendlyProbability::from_probability(0.001);
assert_eq!("<1 in 100", friendly.friendly_string());

请注意，将小于0.0或大于1.0的值传递给FriendlyProbability::from_probability将引发panic。
