# How to keep my real numbers rounded

The following code:

```
var('t')
test(x) = e^(x * t)
test(0.326)
```

gives:

```
e^(0.326000000000000*t)
```

For some reason, Sage converted my "0.326" to "0.326000000000000".

I want to keep the number rounded. i.e:

```
e^(0.326*t)
```

I don't even care if Sage rounds it like this:

```
e^(0.33*t)
```

How can I do this?

I know it is possible to use fractions, E.g, I can use "326/1000" instead of "0.326", but this doesn't look good. All I want is that the floating point numbers remain rounded.
