Rule 10.8 Rationale 3rd paragraph,

"On a 16-bit machine the addition will be performed in 16 bits with the
result wrapping modulo-2 before it is cast to 32 bits."

It will be understood that.

"On a 16-bit machine the addition will be performed in 16 bits with the
result wrapping like modulo-2 before it is cast to 32 bits."

or

"On a 16-bit machine the addition will be performed in 16 bits with the
result wrapping modulo-2^16 before it is cast to 32 bits."

Which do you prefere?

We agree that the following wording would be clearer.

“ On a 16-bit machine the addition will be performed in 16 bits with the result wrapping modulo-2^16 before it is cast to 32 bits.”

where "^" means "raise to the power of"
