After playing with your example a bit more I concluded that the precision
decrease was unreasonable for a simple multiplication and investigated it:

You actually found a precision bug in POV-Ray because the animation loop uses
such an iterative approach by simply adding clock_delta to clock when it goes
from one frame to the next.  This can easily be corrected by applying a proper
multiplication, which should fix this precision problem as well.  This fix
will be in the next beta.
