Good catch. That's caused by a change to the signature of ieeeMean(). Trivially
fixable by inserting casts, though arguably copySign should become a templated
function.

BTW I wrote this code for Tango, it will eventually have a signature change to
match the new Phobos style. It predates ranges, for example, even though it's a
perfect example of a floating-point range-based algorithm. Thus, it's not as
generic as it could be.

Don.
