浮点数Float的常量

Float类中包含多个常量，由于篇幅有限，下面列出部分常量，如下表所示。

   public static void main(String[] args) {
        int size = Float.SIZE;
        int exponent = Float.MIN_EXPONENT;
        float minValue = Float.MIN_VALUE;
        float minNormal = Float.MIN_NORMAL;
        float maxValue = Float.MAX_VALUE;
        float naN = Float.NaN;
        int maxExponent = Float.MAX_EXPONENT;
        Class<Float> type = Float.TYPE;
        float infinity = Float.POSITIVE_INFINITY;
        float negInfinity = Float.NEGATIVE_INFINITY;
        System.out.println("Float.SIZE           " + size);
        System.out.println("Float.MIN_EXPONENT   " + exponent);
        System.out.println("Float.MIN_VALUE      " + minValue);
        System.out.println("Float.MIN_NORMAL     " + minNormal);
        System.out.println("Float.MAX_VALUE      " + maxValue);
        System.out.println("Float.NaN            " + naN);
        System.out.println("Float.TYPE           " + type);
        System.out.println("Float.MAX_EXPONENT   " + maxExponent);
        System.out.println("Float.POSITIVE_INFINITY " + infinity);
        System.out.println("Float.NEGATIVE_INFINITY " + negInfinity);
    }
