How to Convert Between US, EU and Indian Formats
US → European
Remove the commas, swap the decimal dot for a comma, then regroup thousands with dots (French/Russian style uses spaces): 1,234,567.89 → 1234567.89 → 1.234.567,89.
European → US
Strip every dot or space, then turn the decimal comma into a dot: 1.234.567,89 → 1234567.89 → 1,234,567.89. Never swap the two symbols in place — regroup from the plain number.
Any → Indian (lakh/crore)
Normalize to plain digits, group the last three, then pairs going left: 1234567.89 → 12,34,567.89. In words: 1 lakh = 100,000 and 1 crore = 10,000,000.
Golden rule: always normalize to plain digits first, then apply the target convention. Swapping separators in place is risky — 1.234 read as "one point two three four" instead of "1234" is a 1000× error.
