Health officials say these numbers usually increase during this time of year as more Americans cook and eat outdoors.

You can run into issues of things like overflow, underflow, with floating point numbers and when you see a whole bunches of ones, it's particularly a good time to be suspicious.
来看看哪儿会出问题,你可能会碰到浮点数中的溢出和下溢问题,当你碰到一系列这种问题后,可能就会适时的开始怀疑结果的正确性。
So let's take those ideas and go back to the numbers game from last time.
那么我们带着这些方法,回到上次的数字游戏中
And again, how many numbers have I touched physically this time?
这次我真正用了这些数字几次?
Compound that 13.4% over ten years and there's just an enormous gap between those mutual fund numbers that are in the prospectus and in the advertisement--the time-weighted returns and the dollar-weighted returns that talk about the actual experience of the investment community.
按13.4%复利算一下10年期的结果,你会发现在招股说明书和广告里给出的,用来反映投资机构实际业绩水平的,时间加权回报率,和货币加权回报率数字之间,有着巨大的差异
In practice, most of the time we work with these two numbers, Ax and Ay.
在实际过程中,大多数时间我们就用 Ax 和 Ay 来计算
All right, so here once again is our same matrix with me and my pair, choosing actions Alpha and Beta, but this time I'm going to put numbers in here.
我们首先讨论我和我对手,选择α或β的矩阵,不过这次我们用数字来表述
But we also saw it's a dangerous idea to take too literally: that sometimes this can get you to over think the problem and actually, as in that numbers game last time, the best choice, the winning choice, might not involve so many rounds.
同时我们也发现过度照本宣科也不好,有时他会导致你,对于问题的过度探究,正如我们上次玩的数字游戏,最优选择,最后获胜的答案,有时不会绕那么多弯子
At every instant, it's got a location given by the vector R; R itself is contained in a pair of numbers, x and y, and they vary with time.
在每一个瞬时,它的位置由位矢 R 给出,R 本身包含了一对坐标值 x 和 y,并且它们都随着时间的变化而变化
if I say a particle's location is i times t^2 plus j times 9t^3, for every value of time, you can put the numbers in and you can find the velocity by just taking derivatives.
一个质点的位置,i ? t^2 + j ? 9t^3,在每一个时间点,你可以把数值代入,并通过求导得到速度
