You are overthinking it.

If I give you the bit pattern:

000101010111010110100101010001001011100101010

Is that zero or not?

If I give you the bit pattern:

000000000000000000000000000000000000000000000

Is that zero or not?

If I give you the bit pattern:

000000000000000000000100000000000000000000000

Is that zero or not?

If I give you the bit pattern:

100000000000000000000000000000000000000000000

Is that zero or not?

What mental test did YOU use to decide which of those, if any, were zero?
