`hex`¶

hex.add_mul/2 — res += x * dst + carry_dst — one shift-and-add (multiply-accumulate) step used by hex.mul. Reads/writes the global multiplication carry.
hex.add_mul/4 — res[n] += a[n] * b[1]
hex.mul10 — x[n] *= 10
hex.mul — for n==b/2: n^2(5.5@+20)

`hex.mul`¶

hex.mul.clear_carry — Reset the per-multiplication carry-tracking variable to zero. Called by hex.add_mul at the start and end of each addition step (and …
hex.mul.init — dst[1] is zeroed after finishing this multiplication.
