You don't need to calculate the result. You only need to understand where
does the expression come from.
For example, if a cylinder is located at <1,2,3> and another cylinder is
located at <7,8,9>, putting a sphere exactly half-way in the middle of them
is easier to do and understand by writing (<1,2,3>+<7,8,9>)/2 than writing
the result. The result will probably not tell you anything (perhaps you
could guess that it's somewhere between the two cylinders, but you couldn't
be sure without making that calculation anyways).
3/7 is a lot more clear than 0.4285714285

I won't concede my point of view nor will I argue it with you.

Could you please tell me how did I calculate this number?

I)
For my fractal animation ("Warp's Julia Island Forest in Winter,") I
explored 11.85 orders of magnitude in camera angle. My variable for the
camera angle went something like (roughly from memory):
#declare angie=1.2*10^(1-11.85*clock);
Then I could set up a zooming animation, just debugging out the value of
angie with each frame.
II)
Another application involved using the cells pigment in an isosurface to
make a city. The max gradient value has a huge effect on the "quality" of
the image (the diffuse==0 problem for step functions in isosurfaces). I
set up an animation with a variable for max gradient called
#declare maxie=1.2^(33*clock+1);
and added a text object to the animation (roughly from memory)
text_object{"timrom.ttf",str(maxie,3,1),1,0 //blahblahblah
The result was my own tutorial showing me the effect of the max gradient on
the quality of the image.
Oops--this should have gone in p.u.p. :-|
:)

The point was that the evaluation hierarchy in not correct in MP0.5a. For a while
I was fearing that the pov-team and/or the creators of the C language knew of some
kind of "smarter-persons'-hierarchy-they-only-teach-you-in-computer-science."

Perhaps the same way I got this number?

But you've already lost the debate to Ken's superior tactics :)

This one is easy. It was calculated with an electronic calculating
device.

So I suppose the prime factorization of 239 is 239.

You give me more credit than I deserve. I just utilized my internal random
number generator :)
Did someone just say "lame joke"?
