You can either have a big number and a small decimal point or small number and a big decimal point.
可以小数点前面长，后面短,或者，前面短，后面长。
-
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。
-
And there's probably more digits after the decimal place, but because of my formatting string, I only see a couple of them.
这里可能有更多的小数位，但因为我对结果设定了格式，我们只看到两位。
-
You don't need this hack of just, like, manually adding a decimal point just to fix that problem.
你不需要这样来操作，比如，手动地加入小数点来修正这个错误。
-
So a floating point value again is a number with a decimal point, so it depends.
一个浮点型数据就是一个,带小数点的数。
-
But at the end of the day, and here's why we just went with binary and not decimal years ago, when you have one implement a computer with a physical device, it's actually really easy to represent the notion of on or off.
但是最终，之前我们采用二进制,而不是十进制，主要是因为当我们用一台实体机器运行计算机时，这实际上很容易用开或者关的概念来表示。
-
Something with a decimal point and numbers thereafter.
也就是小数点后还有数字。
-
If I go back to that code from a moment ago, and I just rerun math3, notice how many places printed after the decimal point -- two?
如果刚才我回到那段代码中去，我们回到math3，请注意在小数点后面,会打印几位数呢--两位？
-
So it turns out there's a solution to this: If you need more precision, more digits after the decimal point than a float allows, what do you go for instead?
所以这里有一个解决方案：,如果你需要比float类型允许的更高精度，小数点后更多位数,那你该用什么取代它？
-
So unlike an int, this is the type of number that can have numbers after a decimal place.
所以，不同于int，这个类型的数字,可以有小数位。
-
If we need a 7, this is the ones column, the twos, fours, eights, so here are our columns and this was our decimal system a moment ago, and I wanna express the number 7 and the only digits 0 I now have access to are zero and one, whereas, in decimal, dec meaning 10.
如果你需要7，这是一位，二位，四位，八位，这是位数,刚才说的十进制的位数，我想表达7而且,只能采用数字1与，在十进制中，dec意思是十。
