Last Updated : October 08, 2021

Problem Statement

In this program, we will calculate the power of a floating-point number using the powf() function. Here we will use both the number and power of float type.

Program/Source Code

The source code to calculate the power of float number using the powf() function is given below. The given program is compiled and executed successfully.

// Rust program to calculate the power 
// of float number using powf() 
// function

fn main() 
{
    let num: f32 = 3.24;
    let result = num.powf(2.3);
    
    println!("Result is: {}", result);
}

Output

Result is: 14.93666

Explanation

Here, we created a variable num of f32 type with the initial value of 3.24. Then we calculated power 2.3 for the number num using the powf() function and printed the result.
