Assumptions & limits

Assumptions & limits

  • User-supplied weekend eligibility and complete weekend package prices; days round upward in 24-hour blocks. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. Elapsed hours>0; nonnegative tariffs/extras; weekend price null means ineligible; no date-derived tariff eligibility inferred.
