I’ve been using SymEngine to get a symbolic polynomial representation of a function and have been impressed by its speed and amazed that it even works seemlessly with `BigFloat`

. However, at least partially because the function I care about is based on floating point parameters parsed from a file, which were serialized with limited precision, I end up with a lot of terms with coefficients like

```
2.632918509595140993295845084408890582769689363958590871803066577611530482365e-116
```

I’d like to drop those terms. Is there a simple way to do that?
