I've got to manipulate some signed 12bit integer numbers from a file and
apparently Mathematica only handles 8 and 16 bit signed numbers
(probably for a very good reason). So I bring them in as 16 bits (and
they're stored that way with a leading zero nibble) and then I have to
do the following to make sense of them. I really don't know why this
code works but it does.
So to my question: once again I had to resort to a For loop to pull this
off and I know this is a no-no. But I'm so clueless about Mathematica
that I've never come up with a more sophisticated method after a year or
so of thinking about it. Can someone help (as they usually can)?
For[i = 1, i < Length[y], i++, If[y[[i]] > 2048, y[[i]] =
y[[i]] - 2048, y[[i]] = y[[i]] + 2048]];
Thanks, Rob
