How to check this calculation
Formula & conventions
Boards run along the entered length. The calculation finds whole rows covering the width and shows the last board rip width. Joints consider the end gap and usable stock length after trimming.
n = ceil((W + g)/(b + g)); k = ceil((L + gₑ)/(S + gₑ))
