I'm actually just going to do something simple first, print the arguments to this function.
我实际上将要先做点简单的东西,打印函数的参数。
It means anybody using that little function get float doesn't have to worry about what's inside of it. So for example, I decide I want to change the message I print out, I don't have to change the function, I just pass in a different parameter.
这代表着用这个方法去获得浮点数,的任何人都不用担心具体的实现了,例如,如果我想改变下,显示的信息的话,我不必去改变方法,我传个不同的参数就可以了。
