如果该数值位于PHP允许的浮点数值范围之内，那么它就是有限值。
The value is finite if it is within the allowed range for a PHP float on this platform.
如果该数值超过了PHP允许的浮点数值范围之内，那么它就是无限值。
The value is infinite if it is too big to fit into a PHP float on this platform.
这里我声明了一个变量，然后我把那个幻灯片上的公式，用键盘上的字符翻译成了，浮点数值。

它直接把小数点后面的数值丢弃掉了，因为，凭直觉，那些整型数和结果应该是一个浮点数据，但是我需要一个更精确的数值。
It just throws the decimal point away and that's because, again, these are ints and the answer intuitively should be a floating point value, but I need to be more specific.
浮点数最好用来表示象测量值这类数值，这类值从一开始就不怎么精确。
Floating point Numbers are best reserved for values such as measurements, whose values are fundamentally inexact to begin with.
