You can use the `--emit-llvm` flag with rustc to check out the IR. To increase
the optimisation amount, you can use `--opt-level LEVEL`, or just `-O` for an
optimisation level of 2.

Yes, it's a static cast, so llvm should optimise that out.
Do note however that the API has changed in 0.9-pre, and num::cast now returns
an Option. So your code would be:
~~~
let res: T = aVariable / num::cast(2).unwrap();
~~~
LLVM should resolve the conditional at statically - I haven't check
Hi,
just checking performance wise, is num::cast() doing a dynamic type cast or
a static cast.
I'm writing some template code that works on Real and I need sometime to
divide T:Real by 2 or compate with 0 or 1.
I've been using num::zero() and num::one() so far but how about dividing by
2?
