The `round`

function will give you the nearest number with a given number of digits. Note that it only works for real numbers, so you should round the real and imaginary parts separately.

If you just want to display fewer digits, but have sage remember more precision, then you can use python string formatting. See this question.

Maybe something like that ?

```
sage: QQ(real_part(2.00000000000000 - 2.77555756156289e-17*I))

```
