Rust program to calculate the square root of a number using the powf() function

Program/Source Code:

The source code to calculate the square root of a number is given below. The given program is compiled and executed successfully.

// Rust program to calculate the square root 
// of a number using the powf() function

fn main() 
{
    let num: f32 = 16.0;
    let result = num.powf(1.0/2.0);
    
    println!("Square root is: {}", result);
}

Output:

Square root is: 4

Explanation:

Here, we created a variable num of f32 type with initial value of 16.0. Then we calculated the square root of the number using the powf() function and printed the result.
