We use the zero method to test if a number is zero.
(zero? number)
The zero method accepts just one parameter, the number itself, as illustrated in the syntax section.
The zero method returns true if the number is 0 and false if the number is greater or less than 0.
We use the zero method to ensure that the calculations we are making does not include a zero. Thus, we use the zero method to test the number. Let's look at the example below:
(ns clojure.examples.hello(:gen-class));; This program displays Hello World(defn zerro [](def x (zero? 0))(println x)(def x (zero? -1))(println x)(def x (zero? 9))(println x))(zerro)
From the code above:
zerro.0 into the zero method. true because 0 is 0 .-1 into the zero method. false because -1 is not 0 .9 into the zero method. false because 9 is an odd number and not 0.zerro function to execute the code.
