The name of a number 10 3n+3, where n is greater than or equal to 1000, is formed by concatenating the names of the numbers of the form 10 3m+3, where m represents each group of comma-separated digits of n, with each but the last "-illion" trimmed to "-illi-", or, in the case of m = 0, either "-nilli-" or "-nillion".

For higher powers of ten, naming diverges. The Indian system uses names for every second power of ten: lakh (10 5), crore (10 7), arab (10 9), kharab (10 11), etc. In the two Western systems, long and short scales, there are names for every third power of ten. The short scale uses million (10 6), billion (10 9), trillion (10 12), etc.
I.e., if a number x is too large for a representation () the power tower can be made one higher, replacing x by log 10 x, or find x from the lower-tower representation of the log 10 of the whole number. If the power tower would contain one or more numbers different from 10, the two approaches would lead to different results, corresponding to ...
In both scales, names are given to orders of magnitude at increments of 1000. Both systems use the same names for magnitudes less than 10 9. Differences arise from the use of identical names for larger magnitudes. For the same magnitude name (n-illion), the value is 10 3n+3 in the short scale but 10 6n in the long scale for positive integers n ...
-yllion (pronounced / aɪ lj ən /) [1] is a proposal from Donald Knuth for the terminology and symbols of an alternate decimal superbase [clarification needed] system. In it, he adapts the familiar English terms for large numbers to provide a systematic set of names for much larger numbers.
"For the first time since the 1950s, the U.S. produced more energy than consumed at more than 100 quadrillion BTU's," notes Spencer McGowan, a certified investment management analyst. "Renewables ...
In fact, his monthly PayPal statement showed a negative balance of more than $92 quadrillion, which would have made him more than 5,500 times more indebted than the United States government.
the long scale — designates a system of numeric names formerly used in British English, but now obsolete, in which a billion is used for a million million (and similarly, with trillion, quadrillion etc., the prefix denoting the power of a million); and a thousand million is sometimes called a milliard. This system is still used in several ...
