Garage hourly fee with grace and daily maximum: partial hours are not charged · case 04

Garage hourly fee with grace and daily maximum returns a wrong result when partial hours are not charged.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Input {entry, exit (absolute minutes), grace, hourly, daily_max, lost_ticket, lost_fee}; cents. Exit before entry is 'invalid'. A stay no longer than grace is free (grace is not deducted from longer stays). Otherwise each full 1440-minute block costs daily_max and the remainder costs hourly per started hour, capped at daily_max. A lost ticket pays the greater of the computed fee and lost_fee.

Why this case matters

Fee engines bill customers in integer cents; a wrong boundary, rounding stage or cap scope silently over- or under-charges.

One recorded failure
