Exactly. One would expect it to follow conventions. Also see the

I did not time it but I did compare it relative to both my own home
brewed quantity class and to doubles. Our software can take a long time
to compile already and this particular implementation was at least 10x
as slow to compile as doubles. This could have significant impact on
its utility as well; it might be entirely impractical to use in very
large projects that do a lot of computations.
