How to find the ceiling value of a number using ceil() function in Rust

Answer 1

// ceil(self) -> f64 - Returns the smallest integer greater than or equal to self

use std::f64;

fn main() {
    println!("{}", f64::ceil(13.0));
    
    println!("{}", f64::ceil(13.1));
    
    println!("{}", f64::ceil(15.4));
    println!("{}", f64::ceil(15.5));
    println!("{}", f64::ceil(15.6));
    
    println!("{}", f64::ceil(4.4));
    println!("{}", f64::ceil(4.5));
    println!("{}", f64::ceil(4.6));
    
    println!("{}", f64::ceil(-50.0));
    
    println!("{}", f64::ceil(-7.4));
    println!("{}", f64::ceil(-7.5));
    println!("{}", f64::ceil(-7.6));
    
    println!("{}", f64::ceil(0.0));
}
