Description
Divide discount by original and multiply by 100 for discountPercentOfOriginal; subtract discount for finalPrice.
Fixed and percentage discounts act differently and may produce different prices when their order changes. Threshold pricing also depends on whether a new rate applies to all units.
Divide discount by original and multiply by 100 for discountPercentOfOriginal; subtract discount for finalPrice.

}Limitations and assumptions
- The denominator is the original price; no tax, offer eligibility, price-history verification, or rounding policy is applied.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check actual offer terms, item eligibility, taxes, and monetary rounding before applying a computed price.
