rust cube root

To calculate the cube root of a number in Rust, you can use the cbrt function from the std::f64 module. Here's an example:

fn main() {
    let number = 27.0;
    let cube_root = number.cbrt();
    println!("The cube root of {} is {}", number, cube_root);
}

This code defines a variable number with the value 27.0. It then calculates the cube root of number using the cbrt function and assigns the result to the variable cube_root. Finally, it prints the original number and its cube root using println!.

Please note that the cbrt function works with f64 (64-bit floating-point) numbers. If you need to calculate the cube root of an integer, you can convert it to a floating-point number first.

I hope this helps! Let me know if you have any further questions.
