Re: byte and 2s complement

Bytes in java are signed values [-128,127]. I've submitted a ticket to add a ubyte function which simply checks for [0,255]. Note that this only deals with down-casting. Shift functions work on ints, thus you'd need to mask the byte to an int with (bit-and % 0xFF). If you don't do this, then when

I am working with 2's complement hex. It looks like i can get the value of any number by just using byte? e.g.: (byte 0xff32) -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email to clojure@googlegroups.com Note that post
