本文整理了Java中java.lang.Float.equals()方法的一些代码示例，展示了Float.equals()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Float.equals()方法的具体详情如下：
包路径：java.lang.Float
类名称：Float
方法名：equals

Float.equals介绍

[英]Tests this double for equality with object. To be equal, object must be an instance of Float and floatToIntBits must give the same value for both objects.

Note that, unlike ==, -0.0 and +0.0 compare unequal, and NaNs compare equal by this method.
[中]测试此double是否与object相等。若要相等，对象必须是Float的实例，并且floatToIntBits必须为这两个对象提供相同的值。
请注意，与==、-0.0和+0.0不同，使用此方法比较不相等，而NaN比较相等。
