Frequently Asked Questions
What's the difference between US and European number formats?
US format uses commas as thousands separators and dots as decimal points (1,234.56). European format reverses this, using dots for thousands and commas for decimals (1.234,56).
What is the Indian number system?
The Indian system groups digits differently, using lakhs and crores. Instead of grouping by thousands, it groups the first three digits, then groups by twos: 12,34,567.89 instead of 1,234,567.89.
How does auto-detect work?
Auto-detect analyzes your input number to determine the format. It looks at separator patterns and decimal point position to identify whether you're using US, European, or other formats.
Can I format very large numbers?
Yes! The formatter handles numbers of any size, from tiny decimals to very large integers. For extremely large numbers, scientific notation is automatically applied when appropriate.
