[REBOL] Re: Bit-shift operators

From: greggirwin::mindspring::com at: 21-Feb-2006 6:50

Hi Fabien, FT> Are bit-shift operators available in REBOL, to shift (signed and FT> unsigned) integers to the right or left ? Not natively. FT> More specifically, I am interested in getting the bytes of an FT> integer (16 or 32 bits) in big-endian and low-endian order. If you can use a test release that has the rebcode VM in it (see for more info on that), there are bit ops in there, and you can easily wrap mezzanines around them. If that doesn't work for you, I have some old--and probably ugly--code here for twiddling bits with pure REBOL, but it will be very slow by comparison. If you don't need actual shift ops, you might be able to do it another way. Check out this ML thread at to see another approach: -- Gregg
