How do you write this number in words 870349836291.087?

Answer 1

• As I use the long scale (based on powers of a million) as used in counties like Europe I write it as:

870,349,836,291.087 = eight hundred and seventy thousand million, three hundred and forty nine million, eight hundred and thirty six thousand, two hundred and ninety one, point zero eight seven.

• Others, use the short scale (based on powers of a thousand plus one) as used in countries like USA and write is as:

870,349,836,291.087 = eight hundred and seventy billion, three hundred and forty nine million, eight hundred and thirty six thousand, two hundred and ninety one, point zero eight seven.

Note: some people may write the decimal part as "and eighty seven thousandths" instead of "point zero eight seven".
Note: some people using the long scale use "milliard" instead of "thousand million"
