No, you are completely misunderstanding how floating-point precision works.
If what you imply would be true, POV-Ray could not even work at all.

And even if it would matter, as the clock values are internally with single
precision and all declared floats are of course double precision, you probably
even gain precision by calculating them this way...

You didn't read what I said:  "to drop the initial_clock and final_clock in
favor of a start_frame and end_frame"
