大写金额换算器iOS版源码
人民币金额大写转换器输入数字就可以转换成相应的人民币大写金额，操作很easy，需一键点击，就可以复制。
是財务办公人员必备的小工具。
银行、单位和个人填写的各种票据和结算凭证是办理支付结算和现金收付的重要根据，直接关系到支付结算的准确、及时和安全。票据和结算凭证是银行、单位和个人凭以记载账务的会计凭证。是记载经济业务和明白经济责任的一种书面证明。因此，填写票据和结算凭证必须做到标准化、规范化、要素齐全、数字正确、字迹清晰、不错漏、不潦草、防止涂改。
中文大写金额数字应用正楷或行书填写，如壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、佰、仟、万、亿、元、角、分、零、整(正)等字样，不得用一、二(两)、三、四、五、六、七、八、九、十、毛、另(或0)填写。不得自造简化字。假设金额数字书写中使用繁体字，如贰、陆、亿、万、圆的，也应受理。
