Apart from million , the words in this list ending with -illion are all derived by adding prefixes (bi -, tri -, etc., derived from Latin) to the stem -illion . [10] Centillion [11] appears to be the highest name ending in -"illion" that is included in these dictionaries. Trigintillion , often cited as a word in discussions of names of large numbers, is not included in any of them, nor are any of the names that can easily be created by extending the naming pattern (unvigintillion , duovigintillion , duoquinquagintillion , etc.).googol and googolplex , generally crediting it to the Kasner and Newman book and to Kasner's nephew. None include any higher names in the googol family (googolduplex, etc.). The Oxford English Dictionary comments that googol andgoogolplex are "not in formal mathematical use".edit ]Some names of large numbers, such as million , billion , and trillion , have real referents in human experience, and are encountered in many contexts. At times, the names of large numbers have been forced into common usage as a result of hyperinflation . The highest numerical value banknote ever printed was a note for 1 sextillion pengo (10 21 or 1 milliard bilpengo as printed ) printed in Hungary in 1946. In 2009, Zimbabwe printed a 100 trillion (1014) Zimbabwean dollar note, which at the time of printing was worth about US$30. [12] sextillion are rarely used, since in the contexts of science, astronomy, and engineering, where such large numbers often occur, they are nearly always written using scientific notation . In this notation, powers of ten are expressed as 10 with a numeric superscript, e.g., "The X-ray emission of the radio galaxy is1.3×1045 ergs." When a number such as 1045 needs to be referred to in words, it is simply read out: "ten to the forty-fifth". This is just as easy to say, easier to understand, and less ambiguous than "quattuordecillion", which means something different in the long scale and the short scale.
