Is there any real number that starts with J? - Answers

No - at least not in the English language. We have zero (starts with z) one (starts with o) two (starts with t) three (starts with t) four (starts with f) five (starts with f) six (starts with s) seven (starts with s) eight (starts with e) nine (starts with n) ten (starts with t) eleven (starts with e) twelve (starts with t) thirteen (starts with t) fourteen (starts with f) fifteen (starts with f) sixteen (starts with s) seventeen (starts with s) eighteen (starts with e) nineteen (starts with n) twenty (starts with t) thirty (starts with t) forty (starts with f) fifty (starts with f) sixty (starts with s) seventy (starts with s) eighty (starts with e) ninety (starts with n) from there on up, all numbers start with one of these, for example: 35,500,400,122 Thirty five billion five hundred million, four hundred thousand one hundred twenty-two (starts with T) We do have some number related words that we don't actually start the names of numbers with: Hundred Thousand Million Billion Trillion Quadrillion Quintillion Sextillion Septillion Octillion Nonillion Decillion Undecillion Duodecillion Tredecillion Quatrodecillion Virgintillion ... and so forth continuing to use the same types of prefixes with u (un), b(bi) d(duo,dec), t(tri), q(quad, quint), s(sex, sept), o(oct), n(non), c(cent), m(mili), None of them start with "J". The extremely large numbers Googol and Googleplex both start with G. The metric prefixes include kilo mega giga tera peta exa zeta yotta (none of which start with J) and fractional prefixes of deci centi milli micro nano pico femto atto zepto yocto (still nothing starting with J) Informally 10 to the 27th power is called "hella" - as sort of a nerd joke - but still no "J" number.
