/*Ver:1.0 Created By xsb on 2003-8-18 For:
將金額數(shù)字(單位元)轉(zhuǎn)換為大寫(xiě)(采用從低至高算法)
數(shù)字整數(shù)部分不得超過(guò)16位,可以是負(fù)數(shù)。
Ver：1.1 Modified By xsb on 2003-8-20 For:個(gè)位數(shù)處理也放在For循環(huán)中。
Ver：1.2 Modified By xsb on 2003-8-22 For:分后不帶整字。
Ver：1.3 Modified By xsb on 2003-8-28 For:完善測(cè)試用例。
