사용자는 통합 문서 옵션에서 반복 계산을 사용하도록/사용하지 않도록 설정할 수 있습니다.
반복 계산을 사용하지 않도록 설정하면 순환 참조되는 모든 셀의 값이 0이 되고 해당 셀을 참조하는 다른 셀도 0이 됩니다.
반복 계산을 사용하도록 설정하면 모든 값 변경 사항이 iterativeCalculationMaximumChange보다 작아지거나 반복 횟수가 iterativeCalculationMaximumIterations가 될 때까지 순환 참조가 모두 반복해서 계산됩니다.
API는 다음과 같습니다.
iterativeCalculation: 반복 계산을 사용하도록 또는 사용하지 않도록 설정합니다.
iterativeCalculationMaximumIterations: 반복 계산 사용 시 최대 반복 횟수로, 기본값은 1000이고 값 범위는 1~32767입니다.
iterativeCalculationMaximumChange: 반복 계산 사용 시 변화 한도값으로, 기본값은 0.01이고, 값 범위는 0~MaxDouble(1.79769313486232e308)입니다.
isCircularReference 속성이 Events.UserFormulaEntered에 대해 추가되고, 사용자가 순환 참조를 입력하면 이 속성이 true가 됩니다. 예:
getCircularReference 함수로 통합 문서 내 모든 순환 참조를 가져올 수 있습니다. 예:
