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.
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。

the winner is the person whose number is closest to 2/3 times the average The winner will win $5 minus the difference in pennies between her choice and that two-thirds of the average."
所选数字最接近2/3倍平均数人是赢家,赢家的奖金是5美元减去,所选数和平均数三分之二之差的百分数
All right, so I did this not at all purposely, but this can point out for you that you need to make sure that the number of electrons that you have in your molecular orbital does match up with the total number that you have in your atomic orbitals.
我并不是故意这么做的,但这告诉我们必须要保证,分子轨道里的电子数,和原子轨道里的,总电子数能对上。
R And we abbreviate that by calling it r, l by two quantum numbers, and an l as a function of little r, radius.
我们把它简称为,两个指定的量子数n和,它是半径小r的函数。
And the next number is the sum of the previous two.
是前两个的和,再下一个数是前两个数的和。
All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.
好,我试试求2的平方根,我当然不希望得到一个完全准确的答案了,但是我得到了一个近似值,试试将这个数平方一下,你会发现结果和2相当接近。
Knowing that, I'm going to say, OK, how many pigs are there, well that's just how we're, however many I had total, minus that amount, and then I can see, how many legs does that give, and then I can check, that the number of legs that I would get for that solution, is it even equal to the number of legs I started with, ah! Interesting. A return.
它将给我返回头的总数,知道了这些之后我可以说好了,有多少猪呢,无论有多少组鸡的数目,我只要用总数减去那个值,之后我就可以知道一共有多少条腿,然后再把这个值和题目中的腿数相比较,看它是否等于一开始的腿数,啊!真有趣,有一个返回值。
And again, if I just run this, just to show that it's going to do the right thing, it says enter base, I'm obnoxious, it says oops, wasn't a float, so we'll be nice about it and I enter a height, and it prints out what I expected. I just concatenated those strings together, by the way, at the end.
我再来运行下看是不是做对了,提示输入底,噢,它提示说不是浮点数,我很高兴,然后我输入一个,浮点数作为高度显示结果和我预期的相同,顺便说一句,我只是在最后把这些字符串连接起来了。
You know, I was not really disappointed, it found something close enough to 3 that I'm happy.
我真的不失望,因为它找到了一个,和3相当接近的数,我还是挺高兴的。
That is, it's at most the length of the actual number of instructions.
也就是,它至多会执行,和实际指令数一样多的指令。
Well, I could look at the value here, and compare it to the value I'm trying to find, and say the following; if the value I'm looking for is bigger than this value, where do I need to look? Just here.
然后把它和目标数做个比较,然后做出如下的判断:,如果目标值大于这个值;,那么我应该去哪找呢?对,应该在这里,对不对?不可能在那儿。
Initially, it's the beginning and the end of it.
然后根据中值点和目标数的比较结果。
So now, this equation here relates three state functions together: the pressure the volume, and the temperature. Now, if you remember, we said that if you had a substance, if you knew the number of moles and two properties, you knew everything about the gas.
压强,体积和温度,大家应该还记得,我们提过,只要知道气体的摩尔数,和任意两个状态函数,就可以推导出其他的状态函数,这样,我们可以把它改写成。
But that little short hand there is doing exactly the same thing. It is adding that value into some digits and putting it back or signing it back into some digits. And I'll walk through that loop and when I'm done I can print out the total thing does. And if I do that, I get out what I would expect.
加上得到的这个数的,但是这个缩写声明其实是进行了同样的操作,它把我们得到的这个数加到一个数上面去,然后用和对这个数进行了重新赋值,在循环中会去遍历字符串,当完成循环后,程序会显示数字的总和,如果我运行,这个程序的话,我会得到我期待的结果。
Right, I'm going to read in the values of the number of heads and the number of legs.
它看上去和Barnyard完全一样,现在我要读入头数和腿数。
