Do we use the real numbers or do we approximate?

我们是用实数还是用近似值？

The date March 14, as we write it in the United States, is 3-14.

而圆周率日正是由近似值3.14得来。

Estimate, roughly calculate, give an approximation, a good guess.

估计，粗略计算，给出一个近似值，一个好的猜测。

Paul had seen enough for a first approximation.

保罗已经看到足够多的第一近似值。

Because to first approximation, dark matter is invisible.

因为对于第一近似值，暗物质是不见的。

At some point you have to start to approximate values.

在某些时候，你必须开始近似值。

But the best we can really do is offer an approximation.

但我们真正能做的最好的事情就是提供一个近似值。

Estimate, roughly calculate, give  an approximation, a good guess.

估计，粗略计算，给出一个近似值，一个很好的猜测。

As an approximation, however, we can identify this with the rate of interest.

然而，作为一个近似值， 我们以用利率来确定这一点。

And when they come through our radar we get an approximation for position and velocity.

当它们通过我们的雷达时，我们会得到位置和速度的近似值。

These are both pretty good approximations of normal distributions.

这些都是正态分布的很好的近似值。

This means it's approximately equal to, so it's an approximation, not exactly equal.

这意味着它大约等于， 所以它是一个近似值， 而不是完全等于。

It gives you an approximation of how fast, or slow, an algorithm is going to be.

它为您提供了一个算法将要多快或多慢的近似值。

I can't assume that it's exactly, so this is where we're dealing with approximations right here.

我不能假设它是准确的，所以这就是我们在这里处理近似值的地方。

At first I thought that this emission indicated that one of the approximations I had used was not valid.

起初我认为这个发射表明我使用的近似值之一是无效的。

Even this approximation will be approximately normally distributed.

即使这个近似值也将近似服从正态分布。

So it might be pretty good approximation.

所以它能是非常好的近似值。

So we could change this to approximately and we can use our sample proportions.

所以我们以将其更改为近似值，然后我们以使用我们的样本比例。

But I think it'll be a pretty good, in our everyday world as good as we're going to get, approximation.

但我认为这将是一个非常好的，在我们的日常生活中， 我们将获得近似值。

We're going to use some approximations here so don't yell at me if you know exactly how big this tank is.

我们将在这里使用一些近似值， 所以如果您确切知道这个水箱有多大， 请不要对我大喊大叫。
