If it makes you feel any better, "truncX=bitOr(x,0)" is a little bit faster.
Furthermore it works with negative integers, which your formula doesn't. Ofcourse it's
a D8 command and it's not that much faster, really. 13-14% or something. But I think
trunc() would probably be just this much faster if it was built in. ;-)
Anyway, whichever you use, just make it a handler and fool yourself into believing
that the command has been there always. I do that with both trunc and centigrade sine
operations and many other brilliant commands I used to have in my Amstrad Basic as a
kid. (Hey, we all have our preferences, don't we?)
