Not Cluster

[SercoSteveB]

Assuming the value of U8 Numeric, U16 Numeric, U32 Numeric, I8 Numeric, I16 Numeric and I32 Numeric are all set to 1.  What is Output Cluster following execution of the VI?

[MrStevenUND]

D

Can't be B since unsigned cant go negitive.  Assuming NOT is bitwise, C is incorrect for the signed values.  A had no change.

[kasliwal]

D.

'NOT' does bitwise complementation.

I had to look this up: I8 bit representation is interpreted in two's complement format. Therefore

11111110 for I8, gives - 2.

[A.Bernau]

As far as I remember for data representation for signed integer: If most significant bit is set it should be a negativ value and it cant be B how MrStevenUND explained....
answer is D

[LordNobady]

D The not makes the signed negative and the unsigned sty positive. D is the only option.

[crossrulz]

D.  It is doing a bitwise inversion.  From there, you need to know 2's Compliment.

D, for unsigned 8 bit integer the formula would be (255-1), and for Interger it would be (-x-1). I found this on wiki, http://en.wikipedia.org/wiki/Bitwise_operation

Answer: D.  Nice one MrStevenUND, kasliwal, Andreas23, LordNobady, crossrulz, nik35324 & gnshmrthy.
