Line 590 ⟶ 591:
compute delta = ruleval0 + ruleval1 - ruleval
if delta < 0 then
compute abs-delta = -delta
else
compute abs-delta = delta
end-if
compute tol0 = tol * (x4 - x0)
compute tol1 = tol * (x2 - x0)
if (tol1 = tol0) or (abs-delta <= tol0) then
compute delta15 = delta / 15
compute stepval = ruleval0 + ruleval1 + delta15
