Rust program to calculate the cube root of a number

Rust | Calculating Cube Root: Given a floating-point value, we have to calculate the cube root of the given value.
Last Updated : October 08, 2021

Problem Statement

In this program, we will create a floating-point variable and find the cube root of the number using the powf() function.

Program/Source Code

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

// Rust program to calculate the 
// cube root of a number

fn main() 
{
    let num: f32 = 27.0;
    let result = num.powf(1.0/3.0);
    
    println!("Cube root is: {}", result);
}

Output

Cube root is: 3

Explanation

Here, we created a variable num of f32 type with the initial value of 27.0. Then we calculated the cube root of the number using the powf() function and printed the result.
