How to generate a random double number between min and max in Rust

Answer 1

use rand::Rng;

struct GenerateRandomDoubleNumberRust;

impl GenerateRandomDoubleNumberRust {
    pub fn generate_random_double_number_min_max(min: f64, max: f64) -> f64 {
        let mut rng = rand::thread_rng();
        rng.gen_range(min..=max)
    }
}

fn main() {
    let min = 70.0;
    let max = 100.0;

    let d = GenerateRandomDoubleNumberRust::generate_random_double_number_min_max(min, max);
    
    println!("{}", d);
}
