Question

How to compute the hypotenuse h of the triangle in Rust

Answer 1

fn main() {
    let a: f64 = 7.0;
    let b: f64 = 5.0;

    // Method 1: Using sqrt and powf
    let h1 = (a.powf(2.0) + b.powf(2.0)).sqrt();
    println!("The hypotenuse (h) is: {:.6}", h1);

    // Method 2: Using direct multiplication
    let h2 = ((a * a) + (b * b)).sqrt();
    println!("The hypotenuse (h) is: {:.6}", h2);

    // Method 3: Using hypot 
    let h3 = a.hypot(b);
    println!("The hypotenuse (h) is: {:.6}", h3);
}

 
 
/*
run:
   
The hypotenuse (h) is: 8.602325
The hypotenuse (h) is: 8.602325
The hypotenuse (h) is: 8.602325
