floor float rust
In Rust, you can use the floor
function from the num_traits
crate to round a floating-point number down to the nearest integer. To use this function, you first need to add the num-traits
dependency to your Cargo.toml
file:
[dependencies]
num-traits = "0.2"
Then, in your code, you can import the floor
function and use it like this:
use num_traits::Float;
fn main() {
let num = 3.7;
let rounded_down = num.floor();
println!("Rounded down: {}", rounded_down);
}
This will output:
Rounded down: 3
The floor
function returns the largest integer less than or equal to the given number. It operates on any floating-point type that implements the Float
trait from the num_traits
crate.
