How do you say π^π^π?

Well, not that you really probably want to know how to say such an absurdly large number. However for those of you who are interested (allowing for rounding) it is:

one quintillion, three hundred forty quadrillion, one hundred sixty-four trillion, one hundred eighty-three billion, six million, three hundred thirty-nine thousand, eight hundred forty

And yes you can find out how to write your very own absurdly long numbers as well in R! I have adapted John Fox's numbers2words function in order to allow for both absurdly long words as well as decimals. We can see some examples below:

> number2words(.1) [1] "one tenths" > number2words(94.488) [1] "ninety-four and four hundred eighty-eight thousandths" > number2words(-12187.1, proper=T) [1] "minus twelve thousand, one hundred eighty-seven and one tenths" [2] "12,187.1"                                                       > number2words(123) [1] "one hundred twenty-three"
 
You can find the code on github
