How can I convert/read out from a string Hex (8-bit), the bit 0 length 1

[LVdummies]

How can I convert/read out from Hex (8-bit), the bit 0 length 1 (string subset!!??) and convert it to decimal.

With respect to one complement and two complement ?

OK we are going to need more information to help without serious guessing here.

What Type is the data you want to parse?  (String, U8,?)

String to array of U8>> U8 to boolean array>> Index array to get the boolean value for any bit or cast to I8 or U8?  I just can't tell from your discription.

Just like Jeff, purely guessing here.

It almost sounds like you just need to Read from Binary File?

AND the 8-bit number with 1?

Need more details.  What exactly do you have to start with?  What exactly are you trying to get out of it?  Examples help.
