-yllionとは 意味・読み方・使い方

語源

Coined by Donald Knuth in Supernatural Numbers, as a blend of million +‎ -yllion, from English -illion, from French -illion.

接尾辞

-yllion

1. Combined with Latin numeral prefixes to form names of the exponential powers of a hundred thousand / myllion or the squares of such — so that each new name covers twice as many digits. Thus the names myllion, byllion, tryllion, etc.
   • 1981, Donald Knuth, “Supernatural Numbers”, in David A. Klarner, editor, The Mathematical Gardner‎^[1], Boston, MA: Springer, DOI:10.1007/978-1-4684-6686-7_28, →ISBN, Numbers and Coding Theory, pages 310-325:

     The next unit we need after myriads is ${\displaystyle 10^{8}}$. Let's agree to call this a myllion (pronounced mile-yun); similar words like myllionaire will, of course, also be of use. After myllions come byllions; one byllion equals ,${\displaystyle 10^{1}6}$. It clearly is an improvement to have the unambiguous word byllion for this next step, since people have never been able to agree about what a "billion" is. (English かつ German" people think it is a million million, while Americans かつ Frenchmen think it is a thousand million.) Note also the comforting fact that our national debt is only a small fraction of a byllion dollars. The nomenclature should now continue as follows: ${\displaystyle 10^{32}}$ tryllion ${\displaystyle 10^{64}}$ quadryllion ${\displaystyle 10^{128}}$ quintyllion ${\displaystyle 10^{256}}$ sextyllion ${\displaystyle 10^{512}}$ septyllion ${\displaystyle 10^{1024}}$ octyllion ${\displaystyle 10^{2048}}$ nonyllion ${\displaystyle 10^{4096}}$ decyllion ${\displaystyle 10^{8192}}$ undecyllion ${\displaystyle 10^{16384}}$ duodecyllion ${\displaystyle 10^{32768}}$ tredecyllion ${\displaystyle 10^{65536}}$ quattuor-decyllion ${\displaystyle 10^{131072}}$ quindecyllion ${\displaystyle 10^{262144}}$ sexdecyllion ${\displaystyle 10^{524288}}$ septendecyllion ${\displaystyle 10^{1048576}}$ octodecyllion ${\displaystyle 10^{2097152}}$ novemdecyllion ${\displaystyle 10^{4194304}}$ vigintyllion

使用する際の注意点

• The word formed by combining the Latin prefix of a natural number ${\displaystyle n}$ with this suffix means ${\displaystyle 10^{2^{n+2}}}$. So one myllion is “one hundred million”, one byllion is “ten quadrillion”, one tryllion is “one hundred nonillion”, and so on.
