Subject: Least significant bit?


Hi,

Can somebody tell me how to check the least significant bit (bit 0) of a
number?

What I'm trying to do is only to check whether a given number is even or
odd, and (please do correct me if I calculated incorrectly) I think that all
even numbers have 0 as the least significant bit, and all odd numbers have
1, am I correct? Also, is this
 the best/fastest way to do this kind of calculation, or is there something
better?

I've been thinking of doing this with some kind of AND/OR/XOR mask, but I
think that would get way too complex (after all, I'm only trying to read in
ONE BIT!)

Kind regards,

Lionel Pinkhard
