The long scale is a way of writing numbers based on -illion and -illiards (in contrast to the short scale which uses only -illions). Formerly used in the UK, it is generally no longer used in English-speaking countries. Many other languages such as French and German use translated equivalents of the long scale. Numbers in this scale are named due to that they are based off of powers of 1 million

The long scale is used in Epstein system nomenclature.

## Rules Edit

• Separate the number to blocks by three starting from 0.
• Substitute the n-th separator with (n/2)-th Latin prefix. If the position of the separator is odd, then add -illion to the prefix, otherwise add -illiard. The 0-th separator is replaced by thousand.

## Examples Edit

• 65,536 = 65 thousand 536
• 563,535,443 = 563 million 535 thousand 443
• 12,782,303,323 = 12 milliard 782 million 303 thousand 323
• 7,625,597,484,987 = 7 billion 625 milliard 597 million 484 thousand 987
• 59,765,752,000,000,000 = 59 billiard 765 billion 752 milliard
• 1,304,067,000,000,000,000 = 1 trillion 304 billiard 67 billion

## Variations Edit

There is a variation which uses only -illions. In this variation, a full six digit number is put to the right of each -illion so that -illiards aren't needed. One x-illiard is one thousand x-illion.
