There was a problem hiding this comment.
can we make this parameter length_div_16 instead and multiply by 16 in the body of the function -- then the function is total and the caller can prove that it's a multiple of 16 by dividing it by 16 before passing it in.
Consider changing the name to truncate_to_bits16 also
There was a problem hiding this comment.
the input length is a plain integer, which will define the circuit statically, so the caller can't / doesn't have to prove anything about it.
do you still think we should change the signature?
I'm going to change it here but not in the user-facing SnarkyJS method for now (but will throw a quick error there)
