But common languages, and none that I know of which it would be feasible
to write POV in, have a standard, portable facility for writing 128 bit
IEEE 754 floats. You would have to write your own code to do so, if you
just write the floats directly, you will get different results on
different platforms.
And I know it's an easy problem to fix, which is why I called the wide
use of text for numeric values laziness.
