rust number squared
To square a number in Rust, you can use the pow
function from the num
crate. First, you need to add num
as a dependency in your Cargo.toml
file:
[dependencies]
num = "0.4"
Then, in your code, you can use the pow
function to square a number. Here's an example:
use num::pow;
fn main() {
let number = 5;
let squared = pow(number, 2);
println!("The square of {} is {}", number, squared);
}
This code imports the pow
function from the num
crate and uses it to calculate the square of the number
variable, which is set to 5 in this example. The result is stored in the squared
variable and printed to the console.
The output of this code will be:
The square of 5 is 25
