用于检查浮点数是否为无限数的 Java 程序(NAN)
要检查Float是否为isInfinite，请使用该isInfinite()方法并检查NAN，请使用该isNaN()方法。
示例
public class Demo {
public static void main(String[] args) {
float value1 = (float) 1 / 0;
boolean res1 = Float.isInfinite(value1);
System.out.println("Checking for isInfinite? = "+res1);
float value2 = (float) Math.sqrt(9);
boolean res2 = Float.isNaN(value2);
System.out.println("Checking for isNan? = "+res2);
}
}输出结果Checking for isInfinite? = true Checking for isNan? = false
