bitwise right shift is probably the fastest cast to int so far ...
still in many languages, intval is a function call
being a cast in both cases (int) is good as well ... bitwise,
casting, works with strings, arrays, boolean, whatever as well.
I don't think there is any difference in php, except when the
integer is "too big" ... but this was not the case, we had to deal
with 1 to 10 :-)

Subject: RE: [PHP] Need unrounded precision
Hmmm... Didn't think about this, but % only works with int values
it was just future prof precaution since this statement is false
for many other languages.
In few words I am not sure PHP6 does the same ... never mind so far
Good to know. In that case, I would probably just use intval()
instead of >> since it's clearer and bitwise shifts aren't
necessarily integer only either.

I like the bitwise shifting, but here's another potential (albeit
probably slower) solution.
$a = 28.56018;
list (,$dec) = explode ('.', $a);
$b = $dec{0};
