COleCurrency 關係運算子

如果條件為 true 時，比較兩個貨幣值並傳回非零，則為 0。

BOOL operator ==(
   const COleCurrency& cur 
) const;
BOOL operator !=(
   const COleCurrency& cur 
) const;
BOOL operator <(
   const COleCurrency& cur 
) const;
BOOL operator >(
   const COleCurrency& cur 
) const;
BOOL operator <=(
   const COleCurrency& cur 
) const;
BOOL operator >=(
   const COleCurrency& cur 
) const;

備註

注意事項
排序作業 (<、 <=、 >， >=) 的傳回值為 undefined，如果任一個運算元的狀況是 NULL 或無效。等號比較運算子 ()，==!=考慮運算元的狀況。

範例

COleCurrency curOne(3, 5000);             // 3.5
COleCurrency curTwo(curOne);              // 3.5
BOOL b = (curOne == curTwo);              // TRUE

b = curOne < curTwo;                      // FALSE, same value
b = curOne > curTwo;                      // FALSE, same value
b = curOne <= curTwo;                     // TRUE, same value
b = curOne >= curTwo;                     // TRUE, same value
curTwo.SetStatus(COleCurrency::invalid);
b = curOne == curTwo;                     // FALSE, different status
b = curOne != curTwo;                     // TRUE, different status
