RMB Uppercase Converter

This tool converts an Arabic-number amount into Chinese financial uppercase (大写) text suitable for invoices, contracts, and bank drafts. It maps each digit to its anti-fraud character (零壹贰叁肆伍陆柒捌玖), groups the integer part into 4-digit sections with 拾佰仟 inside and 万亿兆 between sections, appends 元, then converts the two decimal places into 角 (tenths) and 分 (hundredths), adding 整 when there are no cents.

1. Enter the Amount as a number (e.g. 12345.67) in the input; the step is 0.01. 2. Click Convert. 3. Read the uppercase output in the result card (e.g. 壹佰贰拾叁元肆角伍分). 4. Click Copy to copy the uppercase string to the clipboard. 5. Use the Examples panel at the bottom as a sanity check (123.45, 1000.00, 100000000).

Digits: 0→零, 1→壹, 2→贰, 3→叁, 4→肆, 5→伍, 6→陆, 7→柒, 8→捌, 9→玖. Positional units within a 4-digit section: 拾 (×10), 佰 (×100), 仟 (×1000). Section units: 万 (×10^4), 亿 (×10^8), 兆 (×10^12). Currency suffix: 元 (yuan), 角 (1/10 yuan), 分 (1/100 yuan), 整 (no fractional cents).
