财务大写规范Financial Uppercase Rules

数字大写使用壹贰叁肆伍陆柒捌玖零,数位使用拾佰仟万亿。金额到元为止时写「整」;到角为止可不写「整」;有分时精确到分。元位为 0 而有角分时,角分前补「零」,如 1.05 → 壹元零伍分。

Uppercase digits are 壹贰叁肆伍陆柒捌玖零 with units 拾佰仟万亿. Amounts ending in yuan add 「整」; ending in jiao may omit it; fen is written exactly. When the yuan part is 0 but jiao/fen exist, a 「零」 is inserted, e.g. 1.05 → 壹元零伍分.

10 元写作「壹拾元整」而非「一十元」,千位空缺补零,如 1005 → 壹仟零伍元整。

10 yuan is written 「壹拾元整」, never 「一十元」; a missing thousand place is filled with 零, e.g. 1005 → 壹仟零伍元整.

使用步骤How to Use

  1. 选择转换模式(数字→小写 / 数字→大写 / 中文→数字)。Choose a mode (Arabic→lowercase / Arabic→uppercase / Chinese→Arabic).
  2. 每行输入一条,支持批量粘贴。Enter one value per line - bulk paste is fine.
  3. 点击「转换」并逐条或整体复制结果。Click "Convert" and copy items individually or all at once.

常见问题FAQ

Q1. 支持到多大的金额?Q1. How large an amount is supported?

整数部分最大支持到「万亿」级,小数精确到分,满足绝大多数财务单据需求。Integers up to the 万亿 (trillion) level, decimals to the fen - enough for virtually all finance documents.

Q2. 0.50 大写怎么写?Q2. How is 0.50 written in uppercase?

写作「伍角整」;0.05 写作「伍分」。元位为 0 时直接以角分开头。It is written 「伍角整」; 0.05 becomes 「伍分」. When the yuan part is zero, start directly with the jiao/fen part.

Q3. 中文小写「一十」还是「十」?Q3. Lowercase: 一十 or 十?

中文小写 10 写作「十」;但财务大写必须写「壹拾」,本工具已自动区分。Lowercase 10 is 「十」, but financial uppercase must be 「壹拾」 - this tool handles the difference automatically.
