Good points, Reimer! I think we also had the newsgroup discussion
recently that
a = 9999.9D ; and
a = double(9999.9)
are different expressions. This is the same kind of problem you were
pointing out in your post. The first case is a native double
precision value. The second case starts out as single precision, and
is converted to double; some precision can be lost in conversion.
