How to check whether a float number is even or odd in Java

Answer 1

public class MyClass {
    static boolean float_even(float f) {
        String s = String.valueOf(f);

        int n = s.charAt(s.length() - 1) - '0';
        
        return n % 2 == 0;
    }

 
    public static void main(String args[]) {
        float f = 23.8713f;
      
        if (float_even(f))
            System.out.println("even");
        else
            System.out.println("odd");
            
            
        f = 23.8716f;
      
        if (float_even(f))
            System.out.println("even");
        else
            System.out.println("odd");
    }
}
