Hi all,

I compute using this code:

```julia
using SymPy

integrate(3+ sin(x^2), (x, 0, 2))

```

The answer is not a single number, but a fraction with Gamma function, which should be able to be computed with Julia, but I do not know how to process this into the final number.

You can use `N` or `evalf` on the output.

Yahoo!! thanks a lot.

So `N` gives more decimals than `evalf`, then it could come in handy in the future.

The `evalf` function can be passed a number of digits to show. `N` is a hacky attempt to match a `Julia` object with the `Python` object. In this case, BigFloat values are returned.
