can someone explain me what the logic operators in binary mode do?

So what is:
-Neg
-Not
-and
-or
-xor
-xnor

thnx

The perform binary operations

1 operator:
Neg = 2's compliment negation
Not = if true then false (sets all bits to the opposite of what they were)

2 operators:
and = if both are true then true, else false
or = if both are false then false, else true (opposite of and)
xor = if one, but not both are true then true, else false
xnor = if one, but not both are true then false, else true (opposite of xor)

actually i like to think of xor as if odd number of 1's then true else false
and the opposite for xnor

[BiTwhise]

that's true

Thank you

Are there advantages of programming in different base numbers? As they say... two minds working together can get a lot done! (that is, human and calculator). Can you use them in 'normal' programs and how can you get them there without using a computer?

I like the thick A-E with hex, if only you could get the whole alphabet.

About the text to matrix post, this is a strange idea, but the ? command used with unique values of variables can allow the user to actually type in a word and the calculator can use the result to process it. Unfortunately, I don't know what values you could use... prime numbers maybe?

You can accept strings from the user and even display them using some tricky algorithims, but I've never been able to find a way to make the letters appear in the same order they were entered.

yea, you would never know the order in which they were entered. You could use it for simple 'yes'/'no' answers and the likes though
