--- Comment #5 from AndyC <andy@squeakycode.net> ---
In dmd 2.066.1, I get:
$ dmd test.d
/usr/include/dmd/phobos/std/math.d(4183): Error: Cannot convert &double to
ulong* at compile time
/usr/include/dmd/phobos/std/math.d(3288):        called from here: isNaN(x)
test.d(4):        called from here: floor(2.3)


Any reason it has to be enum?  Changing it to either const or immutable compiles fine:

pure void main() {
    const double x = floor(2.3);
}

D needs to support basic operations like floor() at compile time too. I change the title of his issue.

std.math.floor is `pure` as of https://github.com/dlang/phobos/pull/1426 and currently works in CTFE.
