Oral liquid volume measured in a dosing syringe: split syringe count · case 03

A 9 mL dose in 5 mL syringes reports a single syringe.

Case contract

Input {weight_kg, mg_per_kg, max_mg, conc_mg, conc_ml (label strength conc_mg per conc_ml), syringe_ml (1, 5 or 10)}. dose = min(mg_per_kg*weight, max_mg); volume = dose/(conc_mg/conc_ml). Graduations: 1 mL syringe 0.01 mL, 5 mL syringe 0.2 mL, 10 mL syringe 0.5 mL. Round half-up to the graduation, but if that delivers more than max_mg round down instead. A rounded volume above syringe capacity returns {status SPLIT, syringes = ceil(volume/capacity)}; otherwise {status OK, volume_ml, dose_mg delivered}.

Why this case matters

Liquid dosing converts mg to mL through a label strength and then to what a syringe can actually measure; each step has a distinct defect.
