}Limitations and assumptions
- Quotes are domestic per foreign currency; this decomposition is order specific and does not model interest, hedging, or transaction-date rates.
- 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 currency direction, quote date, bid/ask conventions, and the full transaction or model before interpreting the result.
