So much for the latest course assessment document in terms of clarifying this issue!

I’d like to re-open this debate.

We are currently debating in school what we need to teach about Integers and Real numbers for SDD at N5.

The latest Course Assessment document states:

The use of binary to represent and store integers and real numbers.

The Specimen question paper q16c asks a question which requires the answer mantissa and exponent despite neither of these being mentioned in the mandatory content.

Do we teach the full current Higher content of floating point representation with examples and then to go onto precision and range?

Similarly with integers, what do we teach? Do we need to teach Two’s complements with examples? If not, then what do we teach about integers?
