FAQ（5）
Which locales are supported?
Any locale your browser’s Intl.NumberFormat understands—for example zh-CN, en-US, de-DE, ja-JP, fr-FR, pt-BR. Availability depends on the browser.
Why JPY looks different?
Some currencies use zero fraction digits by convention; you can override the decimal places in the options.
How are commas handled?
Thousands separators (commas) are stripped before parsing the number.
Does it need a network?
No. Formatting uses the built-in Intl.NumberFormat API offline after the page loads.
Is my amount uploaded?
No. Formatting runs entirely in the browser.
