+# 통화 선택기 컴포넌트
+
+## 개요
+
+Oracle 데이터베이스에서 통화 목록을 조회하고 선택할 수 있는 공통 컴포넌트입니다.
+
+## 데이터 조회
+
+통화 목록을 조회하고, 코드와 설명을 함께 제공해 선택하게 만듭니다.
+
+```sql
+SELECT CD.CD , NM.GRP_DSC
+  FROM CMCTB_CD CD , CMCTB_CDNM NM
+ WHERE CD.CD_CLF = NM.CD_CLF
+   AND CD.CD = NM.CD
+   AND CD.CD2 = NM.CD2
+   AND CD.CD3 = NM.CD3
+   AND CD.CD_CLF = 'SPB032'
+ORDER BY USR_DF_CHAR_8 ASC, CD.CD ASC
+```
+
+## 소수점 자리수
+
+각 통화별 입력가능 소수점 자리수를 자동으로 반환합니다.
+
+- 원화(KRW): 0자리 (정수)
+- 엔화(JPY): 0자리 (정수)
+- 기타 통화: 2자리
+
+## 컴포넌트 구성
+
+### 1. CurrencySelector
+
+기본 선택기 컴포넌트 (버튼 + 다이얼로그 통합형)
+
+```tsx
+import { CurrencySelector } from '@/components/common/selectors/currency'
+
+<CurrencySelector
+  selectedCurrency={selectedCurrency}
+  onCurrencySelect={(currency) => {
+    console.log(currency.CURRENCY_CODE)
+    console.log(currency.CURRENCY_NAME)
+    console.log(currency.DECIMAL_PLACES) // 소수점 자리수
+  }}
+  placeholder="통화를 선택하세요"
+  disabled={false}
+/>
+```
+
+### 2. CurrencySelectorSingleDialog
+
+단일 선택 다이얼로그 (open 상태를 외부에서 제어)
+
+```tsx
+import { CurrencySelectorSingleDialog } from '@/components/common/selectors/currency'
+
+<CurrencySelectorSingleDialog
+  open={isOpen}
+  onOpenChange={setIsOpen}
+  selectedCurrency={selectedCurrency}
+  onCurrencySelect={(currency) => console.log(currency)}
+  showConfirmButtons={true}
+  onConfirm={(currency) => console.log('확인:', currency)}
+  onCancel={() => console.log('취소')}
+/>
+```
+
+### 3. CurrencySelectorMultiDialog
+
+다중 선택 다이얼로그
+
+```tsx
+import { CurrencySelectorMultiDialog } from '@/components/common/selectors/currency'
+
+<CurrencySelectorMultiDialog
+  open={isOpen}
+  onOpenChange={setIsOpen}
+  selectedCurrencies={selectedCurrencies}
+  onCurrenciesSelect={(currencies) => console.log(currencies)}
+  maxSelection={5}
+  onConfirm={(currencies) => console.log('확인:', currencies)}
+  onCancel={() => console.log('취소')}
+/>
+```
+
+## Currency 타입
+
+```typescript
+interface Currency {
+  CURRENCY_CODE: string      // 통화 코드 (예: KRW, USD, JPY)
+  CURRENCY_NAME: string       // 통화 이름/설명
+  DECIMAL_PLACES: number      // 입력가능 소수점 자리수
+}
+```
+
+## 유틸리티 함수
+
+### getDecimalPlaces
+
+통화 코드에 따른 소수점 자리수를 반환합니다.
+
+```tsx
+import { getDecimalPlaces } from '@/components/common/selectors/currency'
+
+const places = getDecimalPlaces('KRW') // 0
+const places2 = getDecimalPlaces('USD') // 2
+```
