Note the increase in correctness of the result by 10 digits.
... which is unintuitive, to say the least;
It isn't any less intuitive than: f + f + 1.3fbeing calculated in 64 or 80 bit precision, which is commonplace, or for that matter:
ubyte b = 200; ubyte c = 100; writeln(b + c); giving an answer of 300 (instead of 44), which every C/C++/D compiler does.
