Do we use the real numbers or do we approximate?

我们是实数还是近似值？

A ballpark figure is a phrase meaning a number which is an acceptably accurate approximation.

A ballpark figure是一个短语，表示一个可接受的准确近似值。

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。

I'm gonna be making a lot of approximations in this calculation.

我在计算时会到很多近似值。

It's an approximation, that's gonna be 0.15 meters.

这只是个近似值，应该是0. 15米。

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。

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。

Because to first approximation, dark matter is invisible.

因为对于第一近似值，暗物质是不可见的。

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。

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。

Paul had seen enough for a first approximation.

保罗已经看到足够多的第一近似值。

Your assumptions, your approximations and the methodologies that you're using.

你的假设、你的近似值以及你使的方法论。

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

然而，作为一个近似值， 我们可以利率来确定这一点。

At some point you have to start to approximate values.

在某些时候，你必须开始近似值。

And this would be even a better approximation.

这将是一个更好的近似值。

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。

Some of them have an explicit criterion that is an approximation of mutual information.

其中一些具有一个显式的准则，该准则是互信息的近似值。

The first approximation, that's not unreasonable.

第一个近似值，这并不无道理。

Yeah, I don't see it quite that way, but we can work with that as an approximation.

嗯，我并不完全那样看，但我们可以把这个作为近似值来使。
