I didn't mean to dispute your anaysis. I think it is correct and I
understood it exactly in the way suggested by your diagram.

It cannot work if you convert using trunc, which is the default "cast"
conversion between float and int.

delay of 1. This will wait until the next tick (time A) which is almost
zero.
I was proposing to use ceil. This will result in 1, except if the input
is exactly 0.0.
