This feels like quite a n00by question so I shall ask it here...

Ok, So I have an 8bit binary number, how do I tell if an individual bit is 1 or 0?

I have looked, but I'm not sure what to call this? so I've not had any luck.

Thanks in advance.

bitwise operators. Pretty annoying to use but... whatever.

>> right bitwise shift
1010101 >> 1 =
0101010

<<left bitwise shift
1010101 << 2 =
1010100

also, the and, or, and xor operators are bitwise.

101011 and
111100 =
101000

110000 or
000011 =
110011

110010 xor
011001 =
101011



[edit] bit truefalse condenses to:
