i thought someone would have done this before, but here is a patch to include an xor binop [^ ] to pd.

this came up because i really wanted a bitwise not... then i realised that when you are dealing with floats, logical not doesn't make any sense (it's not clear how many bits wide the result should be). but then i realised i could fake a restricted kind of not, by xor-ing against an all-ones mask which is as wide as i need.

so: "x ^ 255" is like NOT x when 0 <= x <= 255 (which you could always ensure with an x & 255)

other, more normal uses of xor, i will leave up to your imagination.

included also is a version of the otherbinops.pd help file with the new operator added.

by the way, i'm adding this as a patch to pd because it's too trivial to make a new external for, and it should be in pd anyhow.
