An inquiry into the extremes of Math.ceil
class Test { public static void main(String[] args) { // System.out.println(Math.ceil(10)); System.out.println(Math.ceil(10)); System.out.println(Math.ceil(0)); System.out.println(Math.ceil('c')); //'c' == 99 System.out.println(Math.ceil(0xc)); // System.out.println(Math.ceil(0.1f)); System.out.println(Math.ceil(0.9f)); // System.out.println(Math.ceil(Float.NaN)); System.out.println(Math.ceil(Float.POSITIVE_INFINITY)); System.out.println(Math.ceil(Float.NEGATIVE_INFINITY)); System.out.println(Math.ceil(0.0f)); System.out.println(Math.ceil(0.0f)); // System.out.println(Math.ceil(Float.MIN_VALUE)); System.out.println(Math.floor(Float.MIN_VALUE)); System.out.println(Math.ceil(Float.MIN_VALUE)); System.out.println(Math.floor(Float.MIN_VALUE)); // System.out.println( Math.ceil(Float.MAX_VALUE) == Float.MAX_VALUE); System.out.println( Math.ceil(Float.MAX_VALUE) == Float.POSITIVE_INFINITY); // System.out.println( Math.ceil(Float.MAX_VALUE) == Integer.MIN_VALUE); System.out.println( Math.ceil(Float.MAX_VALUE) == Float.MAX_VALUE); // System.out.println(2 * Float.MAX_VALUE == Float.MAX_VALUE); System.out.println( 2 * Float.MAX_VALUE == Float.POSITIVE_INFINITY); // System.out.println(Float.MIN_VALUE / 2 == Float.MIN_VALUE); System.out.println(Float.MIN_VALUE / 2 == 0.0f); } }
