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

Rust | Calculating Square Root: Given a floating-value value, and we have to calculate the square root of the given value.
Submitted by Nidhi, on October 08, 2021

Problem Solution:

In this program, we will create a floating-point variable and find the square root of the 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.
